There are some additions to my previous sketch. Some more post-processing effects (mainly noise and displacement), two new elements, a new beat detection method, ... But the big change is that I've added some keyboard shortcuts to change "big" variables (frame duration, effects, camera, ...)
Some days ago I rediscovered vvvv. I had seen it when i started using processing, but it seemed at first relatively hard to understand. And since my idea was to code audioreactive applications, processing was clearly dedicated to that ( and at least processing is multiplatform, vvvv only runs on windows).
