Dodecafoam posters

Dodecafoam is a fractal quasicrystalline space-filling froth of dodecahedra which I’ve played with since 1988 in one form or another, and undoubtedly will post more about (check out the dodecafoam tag, or the dodecafoam kits

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

Pages from Topocomix

Doodlebug joins us on a tour of topological surfaces, with drawings and paper and scissor exercises. Another project to complete! Videos of the physical exercises will appear sometime — they do not seem to be

“Lots” of Aperiodic Sets of Tiles

Lots of Aperiodic Sets of Tiles gives intructions for producing more than 25,380 different aperiodic sets of tiles, taken in lots, from a base set of 211 tiles. These tiles allow different hierarchical structures, that

2+√3

This window, in Champions Hall at the University of Arkansas, illustrates a particular twelve-fold tiling substitution scheme: each individual tine may be refined into an arc of smaller tines, and itself sits within a larger

1 of N

This was the second of Eugene Sargent‘s and my collaboration creating participation math art sculptures for the Gathering for Gardner. Here are notes. The fundamental question is, what is N? How many paths were available
