The invention is directed to apparatus and a method of playing a skill game, conducting exercise, or learning movements such as dance steps. Ordinarily, it would be used for contact by the feet, but it could be used for contact by the hands, particularly in connection with physical therapy activity or the like. The contact surfaces are arranged in a coordinated pattern that may consist of a matrix of adjacent colored illuminatable tiles or simply stepping stones positioned in a random array perhaps quite different from a regular matrix. The contact surfaces are illuminated normally one at a time so as to cue sequential steps in a random pattern and at varying speeds in a game. Changes may also be made in a regular repeatable pattern with predetermined timing rhythms of a dance or may be made variable so that they may be slowed or quickened in therapy as the patient progresses. Illumination may be internal as with the tiles, which may be translucent and illuminated from beneath, or may be provided by a movable beam provided with suitable directing means to reposition the beam from one contact surface to another. Switch means are needed for individual fixed lights and may be operated by a switch panel, for example, push buttons which may be provided, one for each contact surface, and arranged in a pattern corresponding to the contact pattern of the surfaces, e.g., a matrix. Other situations for controlling lights may have a means for controlling the lights in a predetermined sequence along a guided path for the controller which preferably can be moved back and forth and over longer or shorter distances as desired. Where beam lighting is employed, a single source of light conceivably could be used, but ordinarily coordinated lights directed to a single contact surface and moved together from one selected contact surface to another are required. These may be coordinated and moved by suitable mechanical drive means controlled by some manually adjusted actuator or by a computer. When tiles are employed they may be built into a frame which permits solid support as well as wiring for illumination and even folding of the frame to provide more convenient portability.
