I found Ishikawa Komuro Lab, part of the University of Tokyo, through one of their YouTube videos (of course). The first video I found was an demonstration of ScoreLight, which is a laser that follows contours and produces sound that changes with curvature and other properties of the curves. There are a lot of movies and demos on their website.

The Khronos Projector is another project that is also very interesting. It uses a touch screen as an interface to a video so that where you touch the screen the movie advances through time.

Here are videos of some of their other research.
