I'm trying to deck out my room with some lasers and strobes like you would see at the trance concert.  Does anybody know any consumer grade light show boxes to buy.  One that would be able to be controlled by the music that is playing.  Thanks

Looks like they have some here.
 
You should check out the Laserium website, too.  I sure wish they still had laser shows up at Griffith Park.  I saw Dark Side of the Moon performed there a few times.
