Abstract
An educational toy (10) having a dodecahedron shape is formed with a different visual display on each planar face (17-28). A position sensing mechanism (50) is oriented inside the toy (10) to inform a microprocessor (62) which one of the planar faces (17-28) is in the "up" position. As the toy (10) is turned or moved a signal is generated to "power on" and a musical tune is played. When one of the planar faces (17-28) is stopped in the "up" position, the position sensing mechanism (50) informs the microprocessor (62) and an aural response corresponding to the visual display is transmitted through a speaker (44). If the toy (10) is left alone for a specified period of time, a warning tune is transmitted. If the toy (10) is still not moved thereafter, the toy (10) will automatically "power off".
