Optical illusions occur when what the eyes see conflicts with what the brain expects.

Eighteen thousand soldiers stood on a parade ground at Camp Dodge, Iowa in 1918 and became the Statue of Liberty when two photographers shot them from an 80 foot tower. 12,000 men filled the flame of the torch alone, while the whole body and head took only 2,000. Many fainted in wool uniforms as the heat neared 105 degrees.
