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

Animal drawings for kids

Working with kids gives me an outlet for drawing cute animal pictures, incorporating them into teaching materials. These are from classroom activities on logic, graph theory and topology, ages 6-12.

“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

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

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

some of the hyperbolic plane illustrations from the Symmetries of Things

These illustrations are from the first edition of The Symmetries of Things, written with John Conway and Heidi Burgiel. Back in the day, kids, I didn’t have a way to actually draw in the computer

Some polyhedral graphics from the Symmetries of Things

Miscellaneous teaching materials

Here are a variety of teaching materials. (Check out the Polyhedra Party repository for the polyhedra stuff especially.)

Some polyhedra to print out and make

These are designed to be printed out or photocopied onto cardstock, cheaply and easily for a classroom activity or multipart curriculum. I’ve put my full polyhedron archive on Dropbox. Here are a few samples of
