I love the iTunes visualizer: it’s great background when I’m working on my other computer or reading, and when he was young, I used it to get my son to fall asleep when he woke up in the middle of the night. I’d put on some Miles Davis, turn on the visualizer, and he’d stare at the screen, fascinated, until he drifted off. Those were the days.

This morning, I ran across an iTunes cheat sheet, which explains all the different kinds of visualizations, color combinations, etc. It turns out that:

There are 11475 form/effect combinations, and 734400 form/effect/color combinations. It would take over 1000 hours to try them all out! And of course you’ll want to try out your favorite ones with different types of music. And if you’re still bored, you can try to experiment with favorite transitions – which should keep you busy for the next 100000 years or so…
