Abstract
A shape matching device includes a frame for rotatably supporting a generally conical container having a plurality of input apertures in a circumferential mantle. Each input aperture is shaped and dimensioned to allow insertion into the container of only one of a plurality of associated blocks. The tapered end of the container is truncated to provide an exit aperture dimensioned for unobstructed ejection of the associated blocks from the container. Along the interior surface of the mantle, a pair of curved longitudinal ribs is provided to support the blocks when the container is rotated in a counterclockwise direction and provide a gravitational slide for the blocks toward the exit aperture.
