I used to draw things like this in PostScript, but it's hard to find a good
PostScript development environment these days, so I'm doodling in Processing.

I've updated it so that it keeps going all the time, varying a small number of parameters until you click the mouse, when it starts anew with entirely different parameters.

OK, now it has the world's worst user interface. I was too lazy to do buttons, so I did keys. Then, you know how it goes, I thought it would be better to do the bad user interface thing whole-heartedly, so I made all the lower-case letters do stuff. There's some documentation on the page, but its default mode is yet another mode, where it draws the same thing over and over. 'a' puts it back in the original, draw one layer mode. 'd' puts it into the most recent, draw every-varying stuff mode.

Even for a bad user interface, it has some quirks I'd like to iron out. But it's amusing.
