Each puzzle piece consist of a six-sided center block, to each end of
which is attached another six-sided center block and a prism block. In the
version shown, a right-handed prism block is at one end and a left-handed one at
the other end, so that each piece has reflexive symmetry and all six pieces are
identical. (Other more complicated versions are possible having dissimilar
pieces.) The puzzle is assembled with no great difficulty by mating two mirror-image
halves to form an interesting polyhedral shape having the appearance of a
cluster of six rhombic dodecahedra. To disassemble it, however, three fingers of
each hand must be placed in exactly the correct places and pushed in opposition
to start the two halves apart along their one sliding axis. Even when made
slightly loose so that it rattles in one's hands, random poking and prying will
seldom dislodge the two halves.
