ABSTRACT:
A light display system adapted for mounting on a rotatable member and capable of generating an image visually perceptible in a reference frame fixed relative to the rotatable member. The display system has a base adapted for mounting on the rotatable member for rotation with the rotatable member about an axis of rotation. Plural light arrays are mounted on the base at angularly spaced locations around a center of the base; each light array has a plurality of lamps. A sensor is operable to detect the fixed reference frame and to provide a signal indicative of the fixed reference frame. A controller is operatively connected to the sensor for receiving the signal from the sensor and is operatively connected to the light arrays. The controller is configured for firing the light arrays in predetermined positions relative to the fixed reference frame to form the image visually perceptible in the fixed reference frame.
