ABSTRACT:
A hollow housing which may be flat or in the shape of a sphere has a map extending over at least part of its outer surface representing at least some of the topographical features of the Earth's surface. The map is formed at least partially by openings in the surface, and a light source inside the housing illuminates the openings so that they will stand out in a darkened room. The openings may be holes at the locations of major cities, cuts extending along the continents and rivers separated by bridges, and cut-outs representing major lakes and inland seas.
