The "Hollow-Mask Illusion" involves tricking the viewer into thinking a negative form is positive.
Creating this effect involved:
1) Making a negative mold from the face of the original sculpt (which is by Jake Hebbert). I used Magic Sculpt for this.
2) attaching that to a positive sculpt of the base
3) Lighting everything in the scene - except the hollow face - with a light from the upper right. I used a gobo on a wire to block light on the hollow face.
4) Lighting only the hollow face with light from the lower left, using an oval mask to shield everything else.
A computer generated version of this is called the "Rotating Mask Illusion."
You can make your own interactive version of this out of paper.

The Haunted Mansion at Disneyland has examples of these, right after you exit the first elevator ("this room has no windows and no doors...")
