Here is a rough cut at the middle of the missing link. Perhaps it is the very essence of the missing link. It starts with the cube expanded to the haptihedron and inverted into the Vector Equilibrium. The VE is built of the closely packed spheres. 92 of them. The 92 spheres move for some reason and in some way and come to rest as an icosahedron. Same number of spheres, arranged slightly differently. To complete the link, invert the icosahedron into the dodecahedron and add them together. Buckminster Fuller called this energy-valve functions, a jitterbug. See section 460 of Synergetics 2.
If you don't see an animation, your QuickTime 3 or movie plug-in is not working. Not to worry, later I'll provide an animated graphic and much much more on this topic.
One aspect of the transformation is that the movment seems to include spirals, both ways. That is some of the spheres move in a clockwise path and others move counterclockwise. Isn't that something?!
