ABSTRACT:
An indicia display characterized by indicia units, either letters or numbers, which, when assembled, create a different visual image depending upon the viewing angle. In addition to direct viewing at a preselected angle, the direct viewing of the reflected image is available through use of a mirror or reflecting surface (where the reflected image is the backside of each indicia unit). The indicia units may be grouped either horizontally or vertically, where the number of indicia units involved is not limited. Virtually all letters, for example, are combinable, i.e. so that each indicia unit presents a different pair of letters, depending upon viewing angle. The indicia units may be carved from wood, cast from metal or molded from a plastic resin.
