TileToy is “a modular, electronic game prototype for tangible LED game tiles” — consisting of four 2-inch squares, each with an LED matrix system. Two videos after the jump.

Each tile is controlled individually and can be used to transmit information on its own or in groups of several tiles. The assembled tiles transmit wirelessly their individual position in relation to each other and based on that changing information, a central computer, or a dedicated tile runs the different applications.
