ABSTRACT:
A device for producing a three dimensional landscape scene within a sand/fluid environment. The device comprises a pair of plates having opposing interior surfaces which define an enclosed plate volume. These surfaces are separated by a distance of 0.02 to 0.06 inches to create a controlled environment conductive for random flow of a variety of sand or particle materials with differing densities and particle sizes. Particular particle sizes and dimensions are provided to enable resolution of colors as the particles fall within the fluid by force of gravity. Three dimensional detail is developed by reason of fine contrast particles cooperating in combination with shading particles and moderate sized particles all entrained within the liquid medium.
