Besides being really cool, what is this? From the standpoint of toys, it is a pull out, push in rolling kinetic toy that can be hung from the ceiling. This is an uber cool example of: science of mechanics, physics, geometry, engineering and art. It is a modern abstract sculpture and a complex scientific mathematical concept that can fit in your hands. It contracts from 5” to 12” being quite a marvel. The design (applauded by architects and industrial designers) consists of small, individual pieces connected by pivoting joints. Better said: this hinge system allows a geometric form, like a sphere or polyhedron, to mechanically blossom or contract while retaining its original shape. This explains its magical, morphing quality which all children can bounce, roll, throw, or just plain analyze and admire.
