Message Wafer
a flat, rectangular card which contains a message. When the wafer is received by the designated recipient, he or she creases the card in the center and cracks it open along the crease. The card can then be folded for standing on a flat surface. The card contains a set of special crystals which will replay the sender's message with video and audio output. When the message is complete, the wafer disintegrates in a flash of light.
