Mini Hoberman Sphere
Stress reliever, brainy hand toy, funny crumpling thing—you decide what you want to call it. But the Mini Hoberman Sphere is one thing for sure: a little bit amazing. Composed of six great circles that correspond to the edges of an icosidodecahedron, it's capable of folding down, in a scissor-like way, to a fraction of its size. It's also a little hard to stop playing with. Spin it on the floor, toss it to a friend, then squash it down to a spiky chrysanthemum shape, and let it rest on your shelf.
