Abstract

Abstract A novelty viewer having a base supporting an enclosure which houses a graphical or simulated scene of a city or the like including a background of opaque material. The enclosure is occupied by a fluid or various fluids of different densities whereby, after shaking, at least two layers of densities result in a color differential promoting an illusion of smoggy conditions above the graphic or simulated scene. The density differential of the layers may be effected by different densities of liquid, by different size and weight of particles or by structurally separated liquid chambers.
