Abstract
This specification describes an amusement device of the kaleidoscopic type where an observer looks down a tube having reflected inside surfaces or planes and usually with two such surfaces at an angle of approximately 45 degrees to one another. The sides of the tube are opaque; but a pair of transparent or translucent discs close the end of the tube opposite the end having the opening for looking along the reflective surfaces. In the prior art loose shapes disposed in the space between the transparent discs tumble over one another as the tube is rotated about its longitudinal axis and interesting designs are formed which appear in the reflectors. The construction of this specification has an opaque wall at the end of the tube and a portion of the tube is made of material that transmits light into the tube to illuminate the opaque end of the tube from the inside. There are no loose shapes in the target.
