RoboSapien sighting
Look closely and you'll find a RoboSapien toy robot on the table in the background. Note the framework of cameras facing him from the piping above, which are tracking many blue LEDs taped to his body, which are then 3D plotted through math magic, and then added to a 3D scene which you can't see because that guy was the most in-the-way guy, and kept popping in front of me whenever I took a picture. Basically they're mocapping the robot toy with a cheap setup. The next image in this Siggraph set features a closeup of the dark robosapien.
