This is my first experiment with the Processing language. I was inspired to try Processing by the amazing Magnetosphere video. Music is a sample of Miss You by Trentmoller. This experiment is using simple OpenGL and the ESS library provides audio playback with FFT.
If you haven't already heard about Photosynth, I recommend you look in to it. I've been following this technology since I first heard about it almost a year ago. Microsoft has since released a demo. There is also a video of a presentation given a TED.
