ID Code: L2-22
Purpose: Illusion with half-silvered mirror.
Description: A single square array of small lights has a full-silvered mirror in back and a half-silvered mirror in front. A long black box placed in back of the infinity mirror appears to have many rows of lights in it until it is removed!

An interesting sidelight is to use this gizzit to indicate the dynamic range of the eye. Each successive row of lights has an intensity of about 1/2. Twenty rows of lights can be seen, so the dynamic range of the eye is at least as great as 220 or 1,048,576 to 1 (actually greater on the bright side)!
