ABSTRACT:
An apparatus (10) for presenting shiftable light patterns includes a translucent globe (12), a convex redirecting mirror (16) mounted adjacent the upper interior surface of the globe (12), a laser beam source (20), a pair of galvanic vibration mirrors (22,24), and amplifier assembly (28) for vibrating the mirrors (22,24) in accordance with a respective pair of stereophonic audio signals (22,24). In operation, the vibration mirrors operate to change the impingement location of the beam on the reflecting mirror in direction in transverse to one another and in accordance with the amplitude and frequency of the audio signals resulting in light patterns which shift in accordance with the audio signals.
