What if art could look back?

Ok, grab a coffee, put your feet up, relax and watch Golan Levin mix art and engineering. How about a robot that is continually surprised to see you - or sounds that make shadows - or bodies that make projected shapes that crash off the projector screen.

Golan begins with a study of a computer mouse wearing through a desk and then takes us on a tour of his latest projects in this TED video.

In terms of understanding ourselves through our art, I get the impression he is just starting to scratch at the surface of what is possible with this technology.
