This posting on Gizmodo about a swanky art-project LED music box reminded me of the far less swanky but considerably funkier Drum Buddy - a crazy home-made light-triggered scratch-able drum box played by New Orleans DJ/Musician Mr Quintron. If you ever see Quintron and Miss Pussycat playing near where you are, it's worth a few quid to see them. Alternatively, you can buy yourself a Drum Buddy for $999 and recreate the vibe at home.
