Abstract: A puzzle emphasizing its three-dimensional character, through its pieces, final form, transparency, and use of color. The completed puzzle, a transparent colored cube, consists of thirty-eight pieces, which are three-dimensional in character, not merely extruded from two dimensions. The solution and appearance of the puzzle is dependent upon its interior structure of form and color. The completed cube, six units to a side, is formed by six truncated pyramids of color. The completed cube is left with a cubic void, two units to a side, at its center. The base of each pyramid acts as a side of the cube. Pyramids opposite one another are of the same primary color: blue, red, or yellow. Pyramids adjacent to one another are of a different primary color. The appearance of the assembled cube changes drastically from different vantage points.
