Anyone know what the music visualizer is?

It's certainly not the real one[0], but looks a lot like the Winamp AVS/MilkDrop stuff. My Inspect Element -fu was however insufficient for getting a closer look.

Judging from the code, it's most likely Butterchurn or some fork.

Didn't Jeff Minter do the Xbox visualizer?
