Magnetosphere is a visualizer for iTunes and the first software release from my current employer, The Barbarian Group. It began its life as a Processing sketch created by fellow Barbarian Robert Hodgin. I translated his design to C++ and then into an iTunes visualizer. From there we continued to tweak the look and optimize its performance. It's still a beta but seems to work well on most computers, so if you're an iTunes user give it a shot and tell us what you think.
