Dancing Light MP3 Synchronizer

When I saw this product, I could only think of one word: groooovy. Okay, maybe that's not even really a word, but look at this Thing. Dancing Light MP3 Synchronizer
is designed to project 33 multi-colored LEDs that are in sync with your music. You can connect the Synchronizer from an iPod or other audio source.
I suppose you might get the same thing off the Windows Media Player, but it can't project onto your ceiling for serious life contemplation to the music. You can also adjust the Synchronizer for the beat of the music, and even match the beats per minute. The Synchronizer requires 3 AAA batteries, and is available for about $40 on the link below.
