Topobo

Topobo is a 3D constructive assembly system with kinetic memory, the ability to record and playback physical motion. By snapping together a combination of Passive (static) and Active (motorized) components, people can quickly assemble dynamic biomorphic forms like animals and skeletons with Topobo, animate those forms by pushing, pulling, and twisting them, and observe the system repeatedly play back those motions.
