A soccer ball is an example of the simplest Fuller sphere, made of 12 regular pentagons and, uh, 20 regular hexagons. Larger shapes can be created by adding more hexagons into the mix, at the expense of roundness: larger Fuller spheres look more and more like dodecahedra (with the pentagons as vertices) than spheres. Any volunteers for working out an adressing scheme for these beasts? :-) -- Nicol N. Schraudolph, C-014 "Big Science, hallelujah. University of California, San Diego Big Science, yodellayheehoo."
