Backlight visualizer for iTunes

I've written about using A le's light up keyboard for purposes other than it was designed for previously, but this is pretty cool. Stefan has written an iTunes visualizer that makes the keyboard lights pulse in time with iTunes.

Now, I don't have an A le portable with a light up keyboard, so I can't test this but if it works that is pretty cool.

Update: You can see this in action here. Sweeeet.
