About a year ago, I went to the Denver Art Museum’s Blink show an saw one of the coolest interactive artworks I have ever seen. It was a projection that looked at you shadow and analyzed it for closed loops. For example, if you made the OK symbol with your fingers, it would turn the shape between your fingers into a surface and fall to the ground making a crashing sound. The larger the surface the deeper the sound. It was awesome!!! Some of the work was done by Golan Levin. Check out his TED talk. ~Cornell
