Wayne Daniel created this magical nesting of the five Platonic solids, a tour de force whose outer icosahedron contained a dodecahedron then a cube, none tetrahedra and four octahedra, all without empty spaces. It garnered attention in the New York Times of May 10, 2005: http://query.nytimes.com/gst/fullpage.html?res=9C06E7DA1230F933A25756C0A9639C8B63 (Decades earlier, Dale Seymour had issued a cardboard model of the five nested Platonic solids, in a different order of nesting.) Both an assembly puzzle and a packing puzzle. Shipped with the Times article, Wayne Daniel's several pages of remarks, and a copy of the Seymour brochure.
