Another study in simple harmonic motion and the nature of complex patterns created from the interaction of multilayered rhythms.
(sounds much better with headphones, seriously)
Here 180 balls are bouncing attached to (invisible) springs, each with a steady speed, but slightly different to its neighbour. Sound is triggered when they hit the floor, the pitch of the sound proportional to the frequency of the oscillation. The total loop cycle duration of the system is exactly 6 minutes.

I prefer the look, sound and behaviour of the previous test vimeo.com/27336153 :) though this one does have interesting patterns too.
