This is anotherProcessingsketch I made recently. This one was supposed to be an exploration of spacing, but went a bit haywire. The circles look at the position of other circles and try to get as far away as possible from other circles. Unfortunately my code was a bit too simplistic, and instead of achieving uniform spacing, I merely pushed them out to the edge of the screen.
I do like the circle and line look though, so you can look forward to it reappearing in the near future, although probably with something a bit more geometric instead of this chaotic sprawl.
The source code is available here.
