A box packing puzzle invented by Leonard Gordon more than 25 years ago. Originally devised from pieces made from joined spheres, here I use truncated rhombic dodecahedra or edge beveled cubes. The eight pieces are identical and sized so that they fit in a golf ball case. If you use 8 colors for the pieces, you will see exactly 5 colors on each face.
Four of the pieces can also be interlocked to form a truncated tetradedron. This is a second puzzle, called "Blossom".
