Claim One:
1. A structure for representing an image haying a plurality of pixels, the structure comprising: a plurality of tile elements held in a fixed relationship to one another, each of the tile elements comprising a generally planar surface inclined at an inclination angle with respect to a reference plane, each of the tile elements corresponding to at least one pixel of the image and having an orientation angle with respect to an illumination direction from which light from a light source is incident on the structure, the orientation angle defined between projections, on the reference plane, of: a line normal to the generally planar surface; and a line parallel to the illumination direction, wherein the orientation angle is determined by a brightness of the corresponding at least one pixel, the structure further comprising a substrate having a surface, wherein the plurality of pixel elements are coupled to the substrate surface, wherein the substrate further comprises a sheet and each tile element further comprises a tab formed from the sheet.
