Close Packing Octahedra, Cubes, Rhombic Dodecahedra 1980, plexiglas, nylon cord, aluminum rods, 30"h x 24"w x 24"d Plexiglas may work - lightweight - transparent - to make close packing forms. Plexiglas planes - held in a rigid structure by tension on nylon cord and compression of aluminum rods - to create space filling tensegrity structures. I construct many close packing pieces. I begin with one of cubes and octrahedra that fill space completely. I make a space filling tensegrity structure of close-packing octahedra, cubes and rhombic dodecahedra. As it rotates its form seems to change - elusive - planes overlap - appear solid - separate - open up - turn to close again. Twenty-seven truncated octahedra close-pack in a tensegrity structure endlessly forming larger and larger cubes - expanding in all directions. The close-packings are sample units of space filling polyhedra.
