XKCD #688 is meta -- it includes information about itself. Why not try and recreate it?. Of course, there are certain inaccuracies. I didn't try and make the bars the exact same width and the like. The last panel doesn't accurately portray the comic, as the resolution isn't high enough. All that aside, this script works in general. It turns out that this is an example of fixed-point iteration. In essence, that's just trying to estimate the original function (which just says this pixel is black, this pixel is white). The core of this algorithm is just a for-loop; the function always returns a correct value for the current estimate! As you might guess (I didn't), this estimate might become unstable. According to Prof. Jarvis Haupt, this algorithm could possibly become unstable. Because the third panel has an infinite regression, it might be possible to set up a non-contractive map where the sequence grows too much and never converges. I couldn't get my comic to be unstable; I'm guessing I could have made long and painful modifications to the code to change it.
