There's an equation that someone came up with in the 1940s that gives the
space-filling solids in any number of dimensions.
There are thirteen space-filling solids in three dimensions.
Penrose tiles are also space-filling in three dimensions.
I wonder how far tiling extends. Can I make a three dimensional analog of a
Ying-Yang? Do Penrose tiles become more complicated in higher dimensions?
Is there a higher dimensional, more irregular tiling past the designs of
Penrose? Penrose tiles seem connected to quasi-tiling in superconductors.
Maybe it's for the same reason that braided wire works better than solid wire?
Too bad I don't have a few spare decades to play with these ideas.

Why lower bus speeds? I'd rather come up with a way that people can build their
own computers at home by reading a PDF and the nearest machine shop.
I've been thinking about photorefractive crystals...
