The original Binary Arts puzzle. It consists of two overlapping circular disks. Each disk has 12 pieces, 6 are triangular, 6 rectangular alternating along the rim of the disk around a hexagonal centre. The disks have three pieces in common. Each disk can be rotated. A rotation has to be a multiple of 60 degrees since only then can the other disk move again. The box is marked © 1996
