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.
