Make your own buckyball by John D. Cook.
From the post:
This weekend a couple of my daughters and I put together a buckyball from a Zometool kit. The shape is named for Buckminster Fuller of geodesic dome fame. Two years after Fuller’s death, scientists discovered that the shape appears naturally in the form of a C60 molecule, named Buckminsterfullerene in his honor. In geometric lingo, the shape is a truncated icosahedron. It’s also the shape of many soccer balls.
Don’t be embarrassed to use these at the office.
According to the PR, Roger Penrose does.
