Abstract
A disk cover is provided with a reflection-type hologram assembly having multiple exposure images therein. The sun or an artificial light source illuminates the hologram assembly as it rotates as a result of the body moving. The exposure images are successively reconstructed to produce a single image that may be remotely positioned from and stationary relative to the rotating disk cover.
