Abstract
The invention relates to structures for representing images by directing light at a viewer. In order to represent an image, a structure is provided comprising a plurality of tile elements (22) 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 (22) may be selected based on a visual characteristic of a corresponding pixel of the 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 (22).
