A system of composing alphanumeric characters and/or decorative designs from modules containing line segments. There are eight different module types (I-VIII), each different module type containing a differently shaped or positioned line segment. Most characters are formed by placing six modules in an array of three high by two wide; those of the module types which are needed to create the desired character are used in the array. Some character require an array only three modules high, while others require an array of three modules high by three modules wide. This embodiment has application in the fields of signage, tiling, games, and educational toys. In another embodiment a system for composing alphanumeric characters and/or decorative designs from compound modules is provided. These compound modules, (XI, XII), are formed by superimposing some of the lines of the eight different module types in one module and then making these lines differentially visible through such means as a LED, LCD, gas-discharge tube, etc.

A system for composing alphanumeric characters and/or decorative designs from modules containing line segments. The line segments within each module are to be provided with means to make each line segment differentially visible, for example light-emitting diodes, liquid crystal displays, etc. The arrangement of line segments within the modules is the means whereby a variety of typefaces previously unobtainable in illuminated lettering or signage is now made available through the use of the present invention. Two module types, each with a different arrangement of line segments within, are herein specified.
