I've been having quite a bit of fun goofing off and programming my entry for Bruce Sterling's Embrace Decay Contest. The contest starts with a 612x800 jpeg of a typing excersize. The contest is to make a series of images that will fade to each other, showing decay.
I started with Diffusion-limited aggregation and then tweaked it to get something interesting. Take a look at my entry! I used to work at Trilobyte, a game company Graeme Devine cofounded. I had forgotten how much fun it is to program graphics. And how tedious. Consider entering.
