Shine a source of light at the back of this mask and look at the concave side. The mask appears to reverse, as if Einstein is looking at you! Move back and forth, and his face turns to follow you. Move up and down, and he nods his head.

The appearance of depth comes from the pattern of shadows that forms on the face. When properly lit, the shadows on the concave mask make it appear to be convex. A fascinating study in how the brain interprets patterns of light! Explanation sheet included. 10 in. high, 9 in. wide.
