Well, it wouldn’t be right if I didn’t start with this one. I was cruising around the internets one day, and I found an awesome flash called pelotas.swf, here for example. It looks only slightly interesting… until you wait for a few moments when everything lines up. Really really crazy stuff.
Sooo, I did some thinking and was able to figure out the algorithm used (some guessing and some pi and such) and came up with CounterClock. I added a few more spirals (variable number actually) and a whole page full of other parameters. Hit the ‘h’ key to see!
