This six-inch diameter paper sculpture is made of sixty identically shaped parts. Parts of any one color form a type of tetrahedron, and there are five such, deeply interlocked. No glue was needed; the parts just hook into each other. I call this type of design "modular kirigami". It took me about four hours to assemble after several hours of false starts and figuring out how to do it. (Addendum: I later added tiny drops of glue at the joints, as I was worried it would vibrate apart in shipping to a gallery.)

Above is a computer-rendered view down a five-fold axis. Observe that the "8"-shaped parts each link with many others. So they could not be made as single pieces of paper unless they were glued or taped together after being linked. But I wanted to be a purist and use no glue or tape, so I designed the parts as two overlapping "3"-shaped pieces. Note the interesting arithmetic:

Below is a view looking directly into a five-fold axis:

This sculpture is described further in my paper in the Proceedings of the 2007 Bridges Conference, available here.
