Bringing M. C. Escher's Planaria to Life
George Hart
(Proceedings pages 57–64)


M.C. Escher's lithograph, Planaria, embodies mathematical ideas that have inspired me to design building kits that can be used to make structures of octahedra and tetrahedra on a human-size scale. The geometric foundations are outlined and a series of designs are shown that culminate in large constructions made of laser-cut plywood.
