  • Patent number: 4021939
    Abstract: Movie-Cubes is a system by which all the surfaces of a group of three-dimensional cubes are patterned in a way that when the cubes are arranged and moved correctly, they create a continuous picture or pattern that changes and eventually returns to itself. The pattern is laid out on a 45.degree. zig-zag graph before it is applied to the cubes. When this group of patterned cubes is arranged, so that the picture or pattern matches from cube to cube, and alternating rows of matched cubes are moved correctly, they create a picture or pattern that not only changes, but eventually returns to where it started. This system operates on the principle of geometric progression whereby, once the group of cubes is matched correctly, they are moved and rotated in alternating rows from one side of the group of cubes to the opposite side. With each rotation and movement of a row of matched cubes, a new part of the picture or pattern is exposed until the picture or pattern eventually returns to its starting point.
