Magnetosphere iTunes Visualizer

http://software.barbariangroup.com/magnetosphere/


This is one of the most beautiful visualizers I've seen.

"Magnetosphere was born of some experiments in Processing that Barbarian Robert Hodgin (of Flight404 fame) was conducting on his experimental blog. "

"There is magnetism, there is gravity, but on top of all of that, there is awesomeness. Watch as all the dots and ribbons go bouncy bouncy when you play music and trigger this mo-fo of a visualizer. This is the future of visuals. God help you if you smoke the reefer cause you can kiss your productivity goodbye. By the way, don't go crazy with the A and S keys - they add or subtract a hundred particles at a time - tap once or twice and wait for the results."
