"Computer Art" is just not a phrase that you hear much anymore. I think it went out of vogue in about 1987, right about the time computers had become so commonplace in homes and offices that any mystique the word "computer" once had had was gone almost entirely. Either way! Computer art, generative art, whatever folks are calling it these days is something I've always had some interest in.
For an illustration project last week I was trying to come up with an abstract background for an image, something that had a similar visual character to models of Calabi-Yau manifolds. Upper-dimensional spaces and what-not. After some unsuccessful paint sketching, I remembered a program I'd written about a year-and-a-half ago in ActionScript that generated these ever-changing, overlapping, intersecting patterns with circles and lines. I fired-up FlashDevelop and started poking around in the source and watching the program go and decided, yep, that was exactly what I needed.
I had a great deal more fun tweaking the program and grabbing stills than I did doing the illustration. So here are some screen grabs to show the kind of stuff I was playing with.
