Post by thread:lights

Hello all, my friends are organizing a concert and they need some kind of light effects. I was thinking in something like the one that appears in the clip from Lenny Kravitz "are you gonna go my way" (anybody remenbers?). My first problem is trying to find the best way to drive all that lamps (more then 200). Does anybody knows any combination of chip/lamp/solution best suited for this ? Thanks.
