From the May 10, 2005 New York Times article on Dr. Wayne Daniel's masterpiece:
The All Five puzzle, as Dr. Daniel has named his latest creation, is a miniature cosmos of its own. On the outside is the icosahedron, inside that a dodecahedron, inside that a cube, inside that a tetrahedron, and at the core a tiny octahedron. Each form is itself a puzzle that must be assembled from interlocking pieces, the whole constituting a tiny symphony of Platonic play.
"This is the first puzzle with all the Platonic solids in a concentric, integrated and solid form, with no voids between them," said Jerry Slocum, a puzzle expert in Beverly Hills, Calif. "It is an amazing achievement."
I so wanted one of these when I was in college. Alas, with a $400 price tag and a waiting list of 171 and counting, I quickly gave up on owning one.
Today, I found out that Wayne Daniel ended up licensing The All Five due to overwhelming demand. I immediately bought one. Although a commercially manufactured model is nowhere near as satisfying to own as a replica handcrafted by the original designer, I'm not complaining. This is a most impressive interlocking puzzle, and easily my favorite.
Now if only I can get my hands on an Astrolabacus.
