How does it work?

This invention is a mechanical structure made of slightly curved links joined by pivots into scissor-pairs. These basic components are connected by hubs into larger units. The opening and closing of the scissor-pairs results in the folding and unfolding, expanding and contracting motion of the Sphere. Like the original Hoberman Sphere, the Mega Sphere is an example of an icosadodechedron. It consists or 20 triangles (icosa means twenty) and 12 pentagons (dodeca means 12). Along with pentagons and triangles, the Mega Sphere is also made up of six circles that intersect each other. The giant size of the Mega Sphere enables a whole new dimension of creative play.
