Wow, I really don’t update this blog very often.

Anyway, for my birthday last year I finally decided to take the plunge and get a 3D printer, something that I had been wanting to do for several years. I did a lot of research including asking some questions at /r/3Dprinting on reddit, and I narrowed it down to two choices:

  1. The Maker Select Plus by Monoprice (the one I was looking at was actually an older version, not the one they show here), which was essentially a re-branded Wanhao Duplicator.
  2. A Prusa i3 Mk2.

On the forums I asked, pretty much everyone agreed that the Monoprice printer was pretty much the best 3D printer you could get for under $300 (the older model was a bit cheaper than the one they have now), and that the Prusa i3 Mk2 was by far the best printer you could get for under $1000, and that the Prusa is far superior to the Monoprice. If you look around online you can find assemble yourself printer kits for around $200 or so, but everyone assured me the quality was a lot worse than what I would get even with the Maker Select by Monoprice.

In the end I decided to take the full plunge and get the Prusa. It’s made and ships from Czech Republic, so with shipping the total cost came to almost $800, not to mention there was about a 5 week wait for my order to arrive. Looking at their site now though, the i3 Mk2 has a 7 week wait time for orders, so they seem to be doing quite well for themselves.

Here’s what you get in the assemble-yourself box:

Assembly took a little while, but I figured it was worth it because 1) it’s $200 cheaper than ordering the pre-assembled printer, and 2) by putting it together yourself you learn a lot about how it works and how to fix any problems that inevitably arise.

And here is the fully-assembled working printer:

Once I got it working, I immediately started printing out all sorts of things that I could download from the internet, mostly on Thingiverse:

You get the idea. I really liked the joystick box, in fact I made two with a raspberry pi and an installation of RetroPie to give my brother and his family for Christmas (just finished it in time!) In fact I liked it so much that I decided to modify it and make my own version, which I then uploaded to share with the community.

I also used it to fix something that broke in the home. My wife has a paper towel holder that mounts to the refrigerator with magnets, but it broke:

I modeled a replacement for the part using FreeCAD, and then printed it out:

And here is the repaired holder:

The biggest limitation it has right now is that I’m mostly limited to printing with PLA plastic, but I’d like to be able to print ABS as well. It’s a bit stronger and more durable, but printing it is a bit trickier: the ABS has a much higher melting point, and so it’s harder to get the printer up to a steady and consistent temperature of 100C compared to just 55C for PLA. When the temperature isn’t consistent throughout the entire bottom printing bed on the bottom, the plastic won’t stick well and you have all sorts of problems. The overall consensus on the internet is that you have to build some kind of enclosure for the printer so that it can more easily maintain a constant high temperature and isn’t subject to drafts in the room, etc. Fortunately it appears that the simple and cheap IKEA LACK table is just the perfect size to contain the printer in and there are plenty of people that have made nice enclosures using them. I’m working on one myself currently. The only real modification I’ll need to do to the printer is that the filament roll will have to come off the top and be mounted separately. Also I’ll probably take the front screen controls off so that I can control the printer while it’s inside the box.

Overall it’s really been a lot of fun, and I highly recommend the Prusa i3 MK2 if you’re looking to take the plunge. Just be prepared to wait a couple of months for your order to come in!

I have two daughters, aged 8 and 10, and they love Star Wars. They both have Star Wars lightsabers, in the past they’ve had both Star Wars t-shirts and pajamas. They love the new Star Wars: Rebels TV show as it’s made for an audience of their age, and it was great to see how excited and invested they were when Kanan faced the Inquisitor in the season finale. We haven’t had a chance to see a lot of the Clone Wars TV show, but we’ve enjoyed watching some of those together as well.

Even with that, they had never seen any of the actual movies. I had been avoiding the movies for a long time, because I have mixed feelings about the films. I loved the original trilogy when it was in its original form, but like many fans I don’t think very highly of all the changes George Lucas made to the original trilogy (Han not shooting first, Jabba at the cantina, Hayden Christensen replacing Sebastian Shaw as Anakin, no more ‘yub yub’ song at the end or Return of the Jedi, etc.) In fact I hadn’t seen the original trilogy myself for over a decade.

And as for the prequels, the kindest word I can have for them is ‘sub-par’. Darth Maul was pretty cool, and… and that’s about it. I didn’t even see episodes 2 or 3 in the theater, instead seeing them later when they came out on VHS or DVD.

But recently I learned about the Despecialized Editions: basically fans going through the painstaking effort of reproducing the original trilogy, shot for shot, as it was in the original theatrical release. Getting hold of them is more than a little laborious, to say the least, but after doing so we watched all three of them during spring break a couple of weeks ago.

It was great.

My 8-year-old daughter had some trouble following some of the plot and dialogue, so I had to pause it periodically to answer her questions, but they both really enjoyed watching them. Some specific comments I recall are:

    “C-3PO doesn’t do anything but whine. He’s kind of like comic relief for the movie.”
    “Why is that old guy [Grand Moff Tarkin] ordering Darth Vader around? Isn’t Vader the main bad guy?”
    “It’s really dangerous to be an officer under Darth Vader. You get promoted quickly, but if you mess up you’re dead.”
    “Han Solo’s a really cool guy.” (this was my 10-year-old daughter, who’s just starting to notice boys a little bit)
    “Why did Jabba make Leia wear that outfit? It doesn’t make any sense.”

I was a little disappointed at the climax of Empire Strikes Back, because they already knew that Darth Vader was Luke’s father. That’s pretty much common knowledge now, so I wasn’t surprised at all that they knew.

However, the two of them were really vested in the love triangle between Han, Leia, and Luke in the first two films, *and they had no idea about the big reveal in Return of the Jedi*. After we finished the first two movies, that was all they could talk about:

    “Leia has kissed both Luke and Han, I wonder which one will she choose?”
    “I think she likes Han Solo more because she told him ‘I love you’, but now he’s frozen and Luke is with her.”

I sagely replied “we’ll just have to watch the next movie and see”.

So I will never forget the look of disbelief and shock on their faces when Luke is talking with the force spirit of Obi Wan in Return of the Jedi and it’s revealed that Leia is his sister. It was great, a true golden moment:

“What??!!”

“That’s impossible!”

“But… they kissed!”

After they recovered from that, they had great fun in seeing Han’s consternation in dealing with Leia. Especially at the end they loved the look on his face when Leia tells him that Luke is her brother. Priceless.

So, now my daughters want to watch the rest of the Clone Wars TV show, and watch the prequels to be ready for Episode VII in December. I have the Clone Wars TV show, but not the prequel movies, so I’ll need to get hold of those next.

I went to see the Tom Cruise movie today, Groundhog’s/Independence Day. I’m not a movie critic so I can’t give a nuanced critique on the movie, but I enjoyed it.

Everytime I see a Tom Cruise movie, I want to not like it simply because of how disturbing I find the whole Scientology thing. But darn it, he’s a good actor, and he does a great job in his movies. I never had any problem with the willful suspension of disbelief necessary to enjoy movies like this. Maybe I should check out Oblivion too.

I actually own the Japanese novel that the movie is based off of, interestingly titled “All You Need is Kill”. I bought it a few years ago before the movie had even been announced, it was recommended to me at the time. However I never got through it. My Japanese reading/writing is a lot weaker than my speaking/listening skills, and it’s really slow for me to read. And if I can’t read it fast enough to immerse myself and enjoy the story, it gets really hard for me continue. Maybe I should give it another try.

Still with much too much free time on my hands, I’ve started re-watching Highlander: The Series, which is conveniently on youtube in its entirety. Some thoughts so far in the first season (which originally showed back in 1992, over 20 years ago!):

The series seems to hold up pretty well overall. The acting is decent, and the casting is good as well. Englishman Adrian Paul is a million times more believable as a Scotsman than Christopher Lambert ever was. Alexandra Vandernoot playing Duncan’s love interest is as exotic and sexy as I remember her, however some parts of 90’s fashion haven’t aged well, which is most noticeable with her costumes: her high-waisted jeans look like mom jeans today, and she (and all the other women in the show) have big poofy hair that looks pretty silly to our current norms.

Production values are good, and it turns out that the show had quite a big budget for a TV show: it was financed and broadcast internationally, allowing it to make profit from numerous markets all over North America, Europe, and Asia simultaneously. With so many financial backers, I don’t know how the producers and directors managed to avoid having everything about the show ruined by a committee, but they seem to have managed it somehow.

Getting Christopher Lambert to do a cameo on the opening episode was excellent: their characters Connor and Duncan McLeod really have great chemistry together, it’s a shame that Lambert didn’t agree to do any more episodes.

Of course my memory tells me that the show really went downhill on the last two seasons, but I’m still on the first season and I’m really enjoying it.

Now is the time of year when my wife and kids go back to Japan for a major portion of the summer, so I find myself with lots of (i.e. too much) free time. While I always have goals of doing something productive, it usually ends up with me playing lots of video games and watching lots of shows or movies.

So I just finished watching a web series called Street Fighter: Assassin’s Fist. Basically it’s 12 10-minute episodes, so total it’s about the length of a full-length film. And I really enjoyed watching it. I’m not extremely knowledgeable about the back story and such of the Street Fighter characters just that Ryu and Ken both use a style called 暗殺拳 (ansatsu ken or assassin’s fist), and that they were both best friends and rivals. I also knew that there was a 3rd character that used the same style named Akuma (Japanese for demon), and that he was antagonist of some sort. That was about it.

Anyway, I was really impressed when I saw it. It wasn’t silly and campy like the old Street Fighter movie with Raul Julia. The dialog is mostly Japanese with subtitles, and in fact all of the Japanese characters are actual Japanese actors, with the sole exception of Ryu played by Asian American Mike Moh. Even then both him and Ken regularly speak Japanese in the show. Overall I’d say that it’s probably the best film based off a video game that I’ve ever seen. If you played Street Fighter back in your youth, I think you’ll like this.

In my last post, I explained the game theory mathematics of the standard game of Rock Paper Scissors (RPS), and what the Nash equilibrium is and how it works. Now I will show a similar analysis, but based on a variant of RPS where winning with rock gets you 1 point, winning with scissors gets you 2 points, and winning with paper gets you 3 points.

We can solve for the Nash equilibrium by doing a probability tree of all the different possible combinations, as before with the standard RPS. In instances where you win, add that many points. When you lose, subtract that many points (your opponent gaining points is equivalent to you losing points). As before, we will choose R, P, and S according to some random distribution, where R is our probability of choosing rock, P is our probability of choosing paper, and S is our probability of choosing scissor. Similarly we define the variables R', P', and S' to be the probabilities chosen by our opponent. Doing so, we get the following expected point gain each time the game is played:

g=0RR' - 3RP' + RS' + 3PR' + 0PP' - 2PS' - 1SR' + 2SP' + 0PP'

Remove the zero terms and then group them by R‘, P', and S':

(-3R + 2S)P' + (R-2P)S' + (3P-S)R'

For the equilibrium condition, we want the total to be 0, and we want it to be independent of whatever our opponent chooses for R', P', or S'. We do that by saying that each of the terms in the parenthesis must be equal to 0. This gives us 3 equations:

\begin{matrix}   -3R + 2S = 0 \\    R - 2P = 0 \\    3P - S = 0   \end{matrix}

Solve the 3 equations for the 3 unknowns, and you get R = \frac{1}{3}, S = \frac{1}{2}, and P = \frac{1}{6}. R+P+S = 1 as it should. You can substitute these into the original equation and prove to yourself that no matter what your opponent chooses for R', P', and S', the expected return is always 0.

So… if you’re one of the 3 people on the entire internet that is still reading this thing, you may be asking yourself, “what about when my opponent doesn’t choose the Nash equilibrium? Is there an optimum R, P, S that will maximize my expected score?”

It turns out there is, and the answer is a quite simple, though getting there takes a bit of algebra. Take the formula for the expected point gain as before (terms equal to 0 eliminated):

-3RP' + RS' + 3PR' - 2PS' - 1SR' + 2SP'

Use R+P+S=1 and R'+P'+S'=1 to eliminate S and S' so it’s only in terms of R, P, R', and P', and define this as a function g(R,P):

g(R,P) = -6RP' + 2P' + 6PR' - 2P + R - R'

Now we have a surface function of two variables, R & P, with R' and P' being constants. We can imagine this being in a 2D domain with R as the x-axis and P as the y-axis. So the domain in question will be a triangle with vertices at points (1,0), which corresponds to R=1 and P=S=0. Similarly, (0,1) corresponds to P=1 and R=S=0, and (0,0) corresponds to S=1 and R=P=0.

triangle plot #1

We could then take the calculus approach and find the local maxima of g(R,P), but we really don’t have to do that. Looking at g(R,P), it is linear w.r.t. both R and P, and so g(R,P) is a flat plane, tilted in some direction determined by R' and P'. Also we know from calculating the Nash equilibrium that g\left(\frac{1}{3},\frac{1}{6}\right)=0 (i.e. when we choose the Nash equilibrium that expected point gain g(R,P)=0 ), and that when R'=\frac{1}{3} and P'=\frac{1}{6} that the plane will be coplanar with the X-Y plane [i.e. when our opponent chooses the Nash equilibrium then g(R,P) will always be zero no matter what we choose, that is only possible when the flat plane is zero everywhere].

Any deviation from those values by R' and P' will cause the plane to tilt in some direction. Since it is now tilting, there will be a direction that increases the value of g(R,P), and since g(R,P) has a constant slope everywhere, the maximum within the triangle-shaped domain must be on one of the points (1,0), (0,1), or (0,0) [or perhaps two of the points will have the same maximum value].

So the optimal choice will either be R=1 (with P=S=0), P=1 (with R=S=0), or S=1 (with R=P=0). Simply evaluating the first equation above for these three choices and seeing which one maximizes the expected point gain will give you your choice.

So for example, here is the surface for g(R,P) we get when our opponent chooses rock, paper, and scissors with equal frequency, or (R',P',S')=\left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right). In our equation S' was eliminated, so for calculating g(R,P) we just need to say that (R',P')=\left(\frac{1}{3},\frac{1}{3}\right):

surface map of g(R,P)

In this plot the gray triangle is the original domain in the previous image, the red triangle is the actual surface of g(R,P), and the black arrow is a normal vector from the plane coming from the Nash equilibrium point at g\left(\frac{1}{3},\frac{1}{6}\right)=0.

It appears that the red triangle is tilted along the R=\frac{1}{3} line, so that both (R,P)=(0,0) and (R,P)=(0,1), or in other words playing scissors every time or paper every time (or some mix of the two) will give you the maximum expected point gain of \frac{1}{3} every time that you play.

Now what if our opponent chooses a strategy that is close to but not quite the Nash equilibrium? How much of a point gain can we expect by using the optimal strategy?

Here is the surface for g(R,P) if our opponent chooses (R',P')=\left(\frac{1}{3}+0.01,\frac{1}{6}-0.01\right):

g(R,P) plot 2

The slope of the response surface is much less, as reflected by the fact that our opponent’s choice of R,P, and S is much closer to the Nash equilibrium. In this case, it turns out that choosing either rock or paper every time will give the optimal point gain, in this case an expected point gain of only 0.03 each time we play.

Of course choosing rock or paper every time would be something that our opponent, if not a mindless robot, would be able to easily capitalize on. What if instead we only slightly perturb our choice of (R,P) away from the Nash equilibrium like our opponent did, but instead perturb it in the direction that gives us the maximum expected point gain?

The distance we move from (R,P)=\left(\frac{1}{3},\frac{1}{6}\right) is the same as our opponent. He moved 0.01 in the R-direction, and -0.01 in the P-direction, for a total distance of \frac{\sqrt{2}}{100}. We know that playing rock or paper every time will maximize our expected score, this corresponds to the line P+R=1. The shortest path to this line is to move perpendicular to it, which is the vector direction (1,1). So this means we should choose the point (R,P)=\left(\frac{1}{3}+0.01,\frac{1}{6}+0.01\right). If we do so, our expected point gain each time we play the game is g(R,P)=0.0012.

My next question is then, how many games do we have to play in order to have, say, a 95% confidence that our score will be greater than our opponent? Remember that what we calculated above is the expected gain, which is kind of like taking a series of many, many games and taking the average. The outcome of any 1 game is random, but after many games we expect to pull ahead slightly. However I’m really rusty on this kind of math and I don’t remember how to do it. I’ll have to review a bit.

Everyone knows the age-old game of rock, paper, and scissors, it’s been around pretty much the whole world for a century or so, and originated in China ~2000 years ago.

Generally the game is approached in 1 of 2 ways: the first is where you try and out-think your opponent, trying to exploit the inherent non-randomness of people when they play the game. This is essentially applied psychology.

The other way to approach the game is where you assume that you and your opponent are totally rational, i.e. both of you know everything about the game and there is no ‘human’ element to exploit. This is essentially game theory.

In game theory, two players are perfectly matched: neither one has any particular advantage over the other. Both players have the same chance to win each game. So the best strategy is to randomly choose rock, paper, or scissors each time (with an equal probability of each).

Using game theory and probability, you can actually prove this. Here’s one way it can be done. Define the following: if you win a game, you get 1 point. If you lose a game, you lose 1 point. R, P, and S are the probabilities of you choosing rock, paper, and scissors respectively. Similarly R', P', and S' are the probabilities your opponent chooses. Obviously R+P+S=1, R'+P'+S'=1, and 0\le R, P, S, R', P', S' \le 1.

Now we calculate the expected point gain per game by taking every possible game outcome, multiplying the point gain/loss of that particular outcome times the probability of it occurring, and then summing them all together. So the points won per game is the following:

g=0RR'-RP'+RS'+PR'+0PP'-PS'-SR'+SP'+0SS'

Since we know that the best choice is to choose R, P, and S with equal probability, then R=P=S=\frac{1}{3}. Since our opponent is also perfectly rational, he will also choose the same probabilities. So the points won per game is:

g=0-\frac{1}{9}+\frac{1}{9}+\frac{1}{9}+0-\frac{1}{9}-\frac{1}{9}+\frac{1}{9}+0=0

Everything sums up to 0, which is what you expect when the game is evenly matched. However, this choice of (R,P,S)=\left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right) lends itself to a very interesting consequence. Let’s say your opponent chooses some (R',P',S')\neq \left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right). What happens then? Let’s say he’s really stupid and chooses rock every time, or (R',P',S')=\left(1,0,0\right). Of course the obvious choice for us to win would be to choose paper every time, or (R,P,S)=\left(0,1,0\right). But if we don’t change our strategy, the following happens:

g=0RR'-RP'+RS'+PR'+0PP'-PS'-SR'+SP'+0SS'
g=0-\frac{1}{3}(0)+\frac{1}{3}(0)+\frac{1}{3}(1)+0-\frac{1}{3}(0)-\frac{1}{3}(1)+\frac{1}{3}(0)+0
g=\frac{1}{3}-\frac{1}{3}=0

Of course, this is obvious without having to calculate it. If your opponent chooses rock every time, and you are choosing each one 1/3 of the time, then 1/3 of the time you’ll tie with rock, 1/3 of the time win with paper, and 1/3 of the time lose with scissors. So let’s see what happens when we choose (R,P,S)=\left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right), but R', P', and S' are still unknown:

g=0RR'-RP'+RS'+PR'+0PP'-PS'-SR'+SP'+0SS'

Rearrange the terms a bit:

g=(0R+P-S)R'+(-R+0P+S)P'+(R-P+0S)S'
g=(\frac{1}{3}-\frac{1}{3})R'+(-\frac{1}{3}+\frac{1}{3})P'+(\frac{1}{3}-\frac{1}{3})S'=0

So we see that for choosing (R,P,S)=\left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right), it doesn’t matter what kind of strategy or ratio that our opponent chooses: the expected point gain will always be zero and we will always be evenly matched with our opponent.

This is what’s called the Nash equilibrium, named after John Nash, the subject of A Beautiful Mind. As I best understand it, for a zero-sum game (of which RPS certainly is), there always exists a state where one player can force the game to remain in equilibrium, no matter what the other player does. For the standard RPS, this comes out to be (R,P,S)=\left(\frac{1}{3},\frac{1}{3},\frac{1}{3}\right). If you choose to play with this distribution, you and your opponent will always be in equilibrium no matter what strategy your opponent tries.

So that brings us to variants of RPS. This whole line of inquiry was inspired by a homework problem that my younger daughter had a few weeks ago. Basically it had a variant of RPS where if you win with rock you get 1 point, win with scissors you get 2 points, and win with paper you get 3 points. Since my daughter is in 1st grade the questions were very easy, i.e. “if you have 10 points and win with scissors, how man points do you have?” etc. But this got me thinking about how this game would actually work. Of course you want to win with paper, but you run into the same problem as regular RPS: you and your opponent are both trying to out-guess each other, so there’s no simple strategy that’s guaranteed to win.

So the next question is, is there a Nash equilibrium for this version of RPS, and if so what is it?

This post is already too long, so I’ll show how to find the Nash equilibrium for this version in my next post.

Back in our younger days, my younger brother and I were quite the aficionados for low-budget martial arts movies. We’re not talking Jackie Chan movies here, those movies are grade-A top quality compared to some of the stuff we regularly watched.

For example, I’ve seen pretty much everything by JKVD made before 2000, almost everything that Cynthia Rothrock has been in, all 3 of the Best of the Best movies (the first is the best of the Best of the Best, though #2 is more entertaining imho), all of the Master Ninja series before I had even heard of MST3K (same goes for Quest of the Delta Knights!), tons of Godfrey Ho Hong Kong drek that was made by editing together unfinished parts of movies (Ninja Death Squad being my favorite example. I could only find that one scene online, but it’s a very representative example), and everything that Billy Blanks did long before he did Tae Bo (which seems to be pretty much dead now).

And speaking of Billy Blanks, probably my favorite fight scene from a martial arts movie is from one of his movies, Showdown from 1993. It’s pretty much a remake of Karate Kid, with Billy in the Mr. Miyagi role and more-or-less unknown Kenn Scott in the Daniel role (seriously, the only mainstream thing he’s done was the suit actor for Raphael in the old TMNT movies).
(more…)

With my wife and kids in Japan, I have been spending a lot more time reading, watching movies and TV shows, etc. Although reading books is usually a personal experience, watching TV or movies is often a social experience. But when you’re a lone, it becomes personal again and I find that I have been exhibiting some strange behavior in that regard. Here are some examples:

1. Reading the book The Name of the Wind, recommended by my brother. So far seems to be an interesting and well-written fantasy novel. However about 1/3 of the way through the book, where the main character is telling his life story (making the entire novel into a story-within-a-story, it seems), when he starts telling about his first attempt at romance, I find myself putting the book down and being unable to continue. I’m not sure why, but since I know it will not end well (since we know from the beginning of the novel that he is not with this girl that obviously it didn’t end well, even though I haven’t read the actual account yet), I find it difficult to continue reading the book. I’ll get back to it eventually, but in the meantime I’ve been reading some ‘lighter’ fare, such as David Edding’s fantasy series.

2. Friday night I watched the brainless action movie ‘Dead or Alive’, based on the titular (that was a joke, get it?) video game of the same name. It’s utterly vapid in such a degree that I couldn’t even conceive of a better villain than Eric Roberts for the movie, but if you’re expecting a brainless and nearly plotless fighting movie that’s heavy on the fanservice, it’s pretty entertaining. However there is a scene where the hacker/nerd character (fitting every Hollywood trope and stereotype of the hacker/nerd) tries to woo one of the supermodel beauties that he has a crush on. I found myself pausing the movie and taking a break, because I knew that he was going to get shot down hard, and I didn’t want to watch that.

Later I continued watching the movie, and it turned out that the writer subverted the trope in this case, and the nerd did get the girl in the end. Probably a wise choice considering the target audience of this movie.

3. Last night I started watching the 1982 movie The Challenge, fish out of water tale where the hapless American protagonist in Japan gets stuck in the middle of the warring factions of a powerful family over the possession a priceless sword. It’s directed by John Frankenheimer (The Manchurian Candidate, Ronin), and the supporting actor is none other than bad-ass legend Toshiro Mifune (who so far hasn’t spoken a single line in English!) Mifune plays Toru Yoshida, the head of the ‘good’ branch of the family who runs a martial arts school. There is a scene where the protagonist Rick (played by Scott Glen), is at a formal dinner with Yoshida’s family and students. Rick gets drunk on sake and does a classic Ugly American, shouting out inane and racist comments in English, completely ignoring the alienating and hostile atmosphere he himself has created, etc. Just watching the scene, I became very uncomfortable and embarrassed. Again I found myself stopping the movie and taking a break, reading a book for a little while.

I actually didn’t finish the movie last night, I ended up going to bed early. But I do intend to watch the rest of the movie this evening.

So what is the deal with me getting uncomfortable enough while watching a movie or reading a book that I actually put it down? It isn’t anything that I find distasteful, sickening, overly erotic, or that I’m simply not enjoying it, but because I find a scene to be embarrassing for the character, and somehow I feel embarrassed by proxy and find it difficult to continue.

Perhaps I’m even projecting myself onto the characters, and recalling experiences in my past where I have been embarrassed or humiliated. Well, looking at the three examples above:

1. First love ending badly? Check.
2. Rejection when asking out a girl who is ‘out of your league’? Check.
3. Being a culturally-insensitive American in Japan? Check.

Yes, all three are embarrassing things I have experienced int he past, and even now I don’t like to recall them. Although my experience with #3 was nowhere near as bad as the scene in the film, when I look back on some of the things I said and did back during my first time in Japan when I home-stayed with a family, I feel a lot of shame and embarrassment.

Is embarrassment and shame by proxy due to self-projection into characters and scenes from books and movies a common occurrence for other people?

We all know about the Pirates vs. Ninjas meme, but what happens when the ninjas are pirates? That’s what happened with last year’s incarnation of the Super Sentai, Kaizoku Sentai Goukaiger (Pirate Warriors Goukaiger). So the Super Sentai are the original form of what becomes the Power Rangers in the US, before they strip out all the scenes with Japanese actors and re-do it all with American (or more recently, New Zealand) actors just keeping the fighting scenes. So ever since Kyōryū Sentai Zyuranger was re-broadcast as the original Power Rangers in 1993, the Power Rangers have always been Ninja-based. They had ninja zords, ninja powers, ninja this and ninja that. In the original Japanese the yearly incarnation wasn’t always so ninja-centric, only Kakuranger in 1994 and Hurricanger in 2002 were specifically ninja-based. Others have been police/detective based, car based, Kung Fu based, and even Samurai based.

However last year’s incarnation was absolutely based around pirates. Here’s the intro if you’re interested. Although Power Rangers have been brought to the US since 1993, in Japan it’s been going since 1975-76, and for the 35th anniversary of the Super Sentai Toei Studios decided to do something special: the gimmick is that the ‘Pirate Rangers’ have stolen the powers of all the previous Rangers, and can call upon their powers during battles. This basically means lots of nostalgia for adults that grew up watching the show, as well as numerous cameos from actors and actresses from former years of the show.

Even though I only knew incarnations from 1992 and onward, it was interesting – and at times appalling – to see the real old-school characters. Probably the most bizarre was Battle Fever J from 1979. Partly inspired by Marvel character Captain America, and partly inspired by the disco craze of the late 1970’s, Battle Fever J had 5 heroes: Battle Japan, Battle France, Battle Cossack (Soviet Union), Battle Kenya and Miss America. It pretty much has to be seen to be believed. Also keep in mind that this came right after the Japanese Spiderman (which btw, can be watched in its entirety on the Marvel website), of which the most normal reaction for Americans seeing it for the first time is this:
spit take
Also in Battle Fever J, it’s painfully obvious that during the fighting scenes that Miss America is being played by a guy. Well, I guess it’s just following a long tradition of Japanese theater. (On the other hand, in Kyōryū Sentai Zyuranger, which became the original Power Rangers, the Yellow Ranger was actually a guy. I wonder what Thuy Trang felt about that?)

So that was a little strange, but I also got so see a bit of some of the really good Super Sentai that have never been translated into English. Specifically, Jetman was the year before Kyōryū Sentai Zyuranger, but is regarded by many as the best of all of them in terms of story. Ryoko and I in fact watched all of it and it was a lot of fun to watch, though much of it hasn’t aged well to tell the truth. Also the original Time Rangers from 2000 is a favorite of many, which in a way is unfortunate because that became Power Rangers: Time Force which was frankly pretty crappy.

If you’re interested in watching Gokaiger, the entire series (with English subtitles), can be torrented here.
