A coordinate motion puzzle. It uses six identical pieces. Assembly requires that all six pieces come together at once. Getting them all at their extreme positions so they can begin to come together is a nearly impossible dexterity problem. At least as difficult to assemble as Rosebud. And not that easy to disassemble either! Number 113 in Stewart's numbering system.
