A high-resolution infra-red camera was loaned to the Interactive Dance Club by Raytheon, and provided another toy for the crowd. It was totally separate from the music and 3D animation with Houdini. The camera was mounted above the dance floor, and its video was projected on a 16-foot screen. From these images you can see that the crowd was heating up over the night. Some people figured out you could draw on the floor with your hand and see the heat-trace on the floor.
