Abstract
Structures for representing images comprise a plurality of tile elements which, when illuminated by a light source, each direct an amount of light toward an observer at a viewing location dependent on their orientation angles. The orientation angles of each tile element may be selected based on a characteristic of a corresponding pixel of an image, such that the observer sees a representation of that image created by the varying amount of light directed to the viewing location by the tile elements.
