Abstract
A system for projecting images on an object with a reflective surface. A plurality of image projectors are spaced around the object and synchronized such that each projector projects an individual image whose union on the surface of the object forms a composite image. The composite image displayed totally covers the surface. The object may represent the Earth with the projected images representing topographical features of the Earth. If environmental satellite data, such as data from a Geostationary Orbiting Environmental Satellite System is used, real time weather conditions may be displayed on this Earth representation.
