Tenori-on! (aka kickass LiteBrite)

I came across the Tenori-on about a year ago but never thought that it would really take flight until today when I came across (somewhat unshamedly from the urbanoutfittersblog) an actually impressive and fun use for the thousand dollar plus synth-lite brite.

Such a good cover, I'm going to make a mental note to learn this on guitar tomorrow....maybe I can rig up some Value Village LiteBrites on some timers and foot pedals to emulate the same effect?
