MoMA Exclusive: Designer Naoki Yoshimoto designed this 3D puzzle in 1971 when he was searching for a way to divide a cube equally. The result, the Yoshimoto Cube No. 1—an object in MoMA’s collection—is an addictively tactile polyhedral dyad composed of eight interconnected cubes that can be configured multiple ways. Divide it into two cubes and then transform the two rhombuses, one silver, one gold, into polyhedrons with 12 faces. With its endless transformations, the cube makes a great toy as well as an intriguing—and calming—desktop puzzle. A MoMA Design Store favorite, the Yoshimoto Cube No. 1 has been recently reissued. It’s made from plastic and polyester and measures 2”cube.
