See "The Oh!" in Belgium.
the place is FULL of TV's. and I really mean FULL of them.
Then there's the DJ and next to him you can see the VJ at work.
it's insane, he's the best i've ever seen. every video played is synched with the beat. eg once there was this song playing, and he decided to cut the parts of Neo in the matrix flying towards the screen. Every kick it changed scene and it was a new background
it was awesome. and pretty hard.. some scenes from Saw were used too. Cutting off fingers or something on every kick. Kinda gross now i think of it.
