INTERACTIVE LCD DISPLAY BACK LIGHT AND TRIANGULATING TOY BRICK BASEPLATE

A baseplate assembly, used with releasably coupleable playing pieces, includes a baseplate operably coupled to an image generating device. The baseplate includes a display region, having playing pieces coupling elements, and means for transmitting images generated by the image generating device to the display region. An image generating and playing-piece-interacting assembly includes a receptor operably coupled to an image generating device, having a display screen for generated images, including integrated visual and optically encoded message images, a playing piece at a location relative to the display screen having an optical display message sensor, and a messaging transponder. The optical display message sensor receives the generated images and generates a first signal at least partially based upon the optically encoded message image. The messaging transponder receives the first signal and generates and sends the receptor a second signal at least partially based thereon.
