This guy. Is AWESOME. Rafael Lozano-Hemmer is an Electronic Media artist who focuses on the “intersection of architecture and performance art.” He makes works that are reliant of interaction from an audience while using a variety of technological media like robotics and computerized surveillance.

Some examples are objects that react to pulse, groups of objects that react when people come close, projections that alter themselves as people interact with them, and using the projections that people create  as canvases for his works. He has art all over the world and he has won a lot of awards for his stuff. His website has TONS of stuff on it, all AMAZINGLY cool.
