Abstract: A unit is described for use in a multi-unit decorative or structural arrangement. Each unit has, on at least one surface, an asymmetrical design which may be two dimensional or three dimensional. These asymmetrical designs are arranged to permit a number of identical units to be arranged together to form a large variety of overall designs whose final form depends upon the relative positions of the individual units within the arrangement. For example, a number of identical square tiles are provided, each having the same design and with the design created so that a tile wall can be formed from the identical tiles with hundreds of different overall designs. The same large number of overall designs may be formed from units other than square units including three dimensional building blocks and similar basic decorative or construction units.
