Various crystallographic space groups
Only a few of these illustrations made it into The Symmetries of Things, but there aren’t such constraints here, and so I present a whole lot of pictures of the non-isotopic, or “composite’ crystallographic symmetries.
The Omnitruncated Dodecaplex
Assembled in one day from about 20,000 zome parts, this was a model of the omnitruncated dodecaplex, hung in Mullins Library. The model took about 200 people-hours to assemble, on November 18, 2010, coming down
Pictures of the kids when they were little
Needless to say, these didn’t make it into the Symmetries of Things. The first pair were rendered in Tess, a program by Chris Watley in 1992 for the NeXT computer. The latter images are seamless
