As I was looking for more videos, I came across videos by a dance theater called Pilobolus. They use shadows of their bodies to create images on a light screen. Probably some of you know about them, but I have never heard of or seen them before. They are pretty amazing!
This is a video from their performance at Late Night show with Conan O'Brien (i love the dog in the video it just made me smile :)
here's a Hyundai commercial. this is an incredible way of art!
