Chuck Hoberman

In addition to toys such as the Hoberman sphere, the largest of which resides at Liberty Science Center in Jersey City, New Jersey, Hoberman created the BrainTwist, a hard plastic tetrahedron that folds, stellates, and becomes self-dual while having a component that rotates similarly to a Rubik's Cube.

Hoberman also has designed folding architectural structures like the Expanding Hypar (1997) at the California Museum of Science and Industry, the Hoberman Arch, the centerpiece of the medals plaza for the 2002 Salt Lake City Olympics, to a retractable dome featured at the World's Fair 2000 in Hanover, Germany.

Hoberman Arch

The arch was designed by Chuck Hoberman to be used as a mechanical curtain for the Olympic Medal Plaza's stage.

Hoberman sphere

A Hoberman sphere is an isokinetic structure patented by Chuck Hoberman that resembles a geodesic dome, but is capable of folding down to a fraction of its normal size by the scissor-like action of its joints.
