Wow. The visualizer is wire-frame happy. Prob. works better as a screensaver than an iTunes visualizer in most instances, because very little focus of the varying amplitudes and frequencies is placed on the various shapes and forms of the centrifigure. In addition, the varying up and down amplitudes as "seen" in the waves in the figure seem to be expressed as a linear function (ex. 256Hz at x = 5, 512Hz at x = 6, 768Hz at x = 7, 1024Hz at x = 8 etc.). I prefer visual representations of sound in powers of 2.
The only thing I found worthy of some notice in the visualizer was the blanket-like wireframe that uniformly rippeled outward from the center, showing evidence of a 3D wave.
What I think would be a cool lookover for a visualizer (excuse the axis in the following image) would be a non-wire frame 3D supercolor representation as follows:
