Abstract

A method and apparatus for displaying an image on a rotatable wheel. A computer processing system is mounted on an inward face of an overcap mountable on the rotatable wheel. Light emitters are mounted on an outward face of the overcap, the light emitters responsive to light emission signals from the computer central processing system. A slip ring assembly is axially mounted on an inward face of the rotatable wheel, the slip ring assembly adapted to provide electrical power to the computer processing system. A trolley assembly is fixedly mounted to a chassis such that the trolley assembly is axially aligned with the slip ring assembly, the trolley assembly adapted to couple the electrical power to the slip ring assembly. Displayable image signals are provided to the computer processing system, the computer processing system adapted to transmit the light emission signals corresponding to the image to the light emitters.
