(Did you mean “ceylon”?)
So whenever there’s a new platform or language or framework I want to learn, and it can like draw pixel-at-a-time pictures, I write a little one-dimensional cellular automaton program for it. (The Java-applet one used to be on my work homepage, but that was apparently at least one iteration of the work homepage ago, and it’s not there anymore. Wonder what I did with that…)
I am veeeeeery sleepy and not up to explaining cellular automata or meta-rules or the serendipitous exploration of logical spaces, or what the buttons actually do, or anything. I wrote down some words on the page that probably say some things.
Also you can read the source code. :D Or just click on various things…
