The present invention is a light producing ball which produces a light in one or more areas of the ball depending upon the orientation of the ball with respect to gravity. A tone generator and speaker are included with the ball to provide unique audio tones for each orientation of the device. Switches and timers are provided to control the volume output and rate of generation of tones and light signals by movement of the ball through a predetermined series of positions, thereby obviating the need for external switches. Automatic turn-on and shut-off is provided to increase power source life.
