I was just playing with iTunes and hit some random keys while visual effects were on (as you do.) And the keys did stuff!
Now I might be a bit slow on this, but, chances are, there are others out there who didn't know about this. So here's a list of what the keys do when visual effects are on:
H or ?: help
F: show/hide frame rate
T: toggle frame rate capping
B: show Apple
I: track info
Q or W: change pattern
A or S: change shape
Z or X: change colour
N: toggle high contrast colours
R: random config
C: current config
M: freeze config
D: defaults
Cool, eh?
