Abstract: An interactive game board or pages of interactive paper are attached to a platform designed to channel power to the game board/interactive paper and to receive signals therefrom. A transmitter unit that is removably attached to the platform provides power to the platform and transmits signals from the game board/interactive paper to a multimedia source, such as a computer or a CD-ROM player. Signals are generated at the interactive game board and interactive paper by means of touch pads that each permit completion of one of a plurality of distinct electrical circuits. Play pieces capable of generating a unique signal through the game board are also provided.

Abstract: A modular binder is provided for quickly and easily binding a sheaf of papers to form a book. The modular binder comprises a pair of cover modules each including a cover leaf hinged to a spine segment, wherein the spine segments are identical and are adapted to interfit in face-to-face relation to retain the sheaf of papers.

Abstract: A three-dimensional jigsaw puzzle sculpture is provided for use in retaining puzzle pieces in assembled form in a decorative piece of art. The jigsaw puzzle sculpture includes a frame which defines the shape of the sculpture, and puzzle assembled to the frame. The frame has a three-dimensional configuration and includes a channel extending around the periphery of each frame section to hold the puzzle pieces in place. Each frame section provides a substantially planar surface circumscribed by a channel, which planar surface provides a support for the puzzle pieces. The planar surfaces include one or more apertures which are utilized to remove the puzzle pieces from the frame. Separable frame members are assembled to one another utilizing pin and hole interlocks. The three-dimensional jigsaw puzzle sculpture, when fully assembled, provides a decorative piece of art which may be subsequently disassembled and reassembled as desired.
