1. Run & watch. 2. Go look at IL's original project; this is 99% his work.
I made several little changes, including: Keep the bells going in the same direction instead of changing direction when they hit the "play" line. Tweaked the math to avoid rounding errors (8.3? Why?!) Let it play multiple notes simultaneously when the bells hit the play line at the same time; chords instead of glissando. Probably other stuff too. I love to see patterns emerge from seeming chaos.
