I used the Chronos high-speed camera to create an effect similar to Bullet Time in which the camera moves instantaneously (or just very quickly in this case).

Heat-sensitive 3D paper (swell paper)

This paper has an unusual coating that swells up when heat is applied. It's normally used by printing on it with a standard inkjet or laser printer, then exposing it to a very bright light.  The dark areas absorb more energy, and become raised.  I also experiment with the material in a laser cutter.  - Source of the paper used in this video - Video about the U Michigan group
