Here’s a little Flash demo that I made back in college. It creates a pattern by snapshotting a circle that bounces within the frame, as determined by user set variables. Specific directions are on the page. This was really an experiment in UI design; how to program tabs, sliders and a play-head, and organizing those elements in an intuitive manner. Looking back, I’d like to have added a randomize button (for each setting as well as all at once) and the ability to save playbacks. The tabs could stand to be a little taller and spaced out a bit more. The velocity settings don’t quite work the way that I’d intended, though I was happy with the results at the time.
