You know, I've been using processing for 2 1/2 years now, and I'm still amazed by the examples. They (usually) manage to be maintain their code elegance yet do fancy and artsy things.

(Some of that, I realize, is in the convention that if you just use one argument to a color-type function, it defaults to a shade of gray, which seems to encourage a nicely reserved aesthetic quality, and avoid the worst of Angry Fruit Salad.

It's a little intimidating, actually... there's so much in recent versions of Processing, and my own kinetic aesthetic sense is a bit underdeveloped, that it seems like it's hard to live up to the potential there!
