iTunes visualizer plugin

Normally we editors of DoseNation wouldn't be so cheesy as to post a ROXXOR SKREEN SAVR D00D but I thought the developer's description of this made it topical:

Here is this thing that does stuff in iTunes. 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.

Ha ha!

I know everyone is into that electric sheep thing nowadays, but frankly if I'm going to be tripping out to visuals I want something a bit more consistent. Sheep has a tendency to jump from one theme to another unpredictably; it's highly cool from a technical point of view, and from a global-meme-engineering-overlord point of view, but it doesn't interact with the music, and it doesn't put me in a trance...

I haven't played with this one (magnetosphere) much yet, so I can't say how AWESOME it is or isn't. Sorry! I will say that the demo video at the link is pretty cool, though.

You know, it just occurred to me, at this point it should be possible to run independent component analysis on an audio signal to pick out some approximation of the individual instruments, and then write visualizer code that would actually respond separately to the elements of the music which would be perceived as separate. I'll have to look into that...
