Let’s make some cool stuff! These are what has been done, and there’s so much more!
Contact me at [[myname]]@gmail.com and let’s talk! (I’ll send a MoMath Speaker Request form.)

The Klein Quartic
here it is made out of paper:

Zome Spectacles
Any shape or size of volume of space can be filled with wonderful Zome structures. These giant spheres resided in a three-story cylinder — we can make flatter panels or ceilings of 5 dimensional crystals and other forms.

Sidewalk chalk math art
Stencils are a fast way to make fun varied patterns

Any parking lot or large sidewalk can become a piece of mathematical art, using strings as straightedge and compass. Here are a couple of examples from a 2005 summer course on projective geometry:

New York’s hexagonal pavers are a special opportunity all over the city, for cellular automata art, polykite tiles and math games and puzzles. I haven’t done this with a group and don’t have photos. Let’s make some art and take some pix!
Many times I led group sidewalk chalking sessions, making topological and geometric drawings from special how-to-guides. I don’t have any photos. Let’s do this again and get some!
Bamboo Spectacles
This was a mainstay of mathematical participation art in Fayetteville Ark. ca. 2004-2010; it is easy to weave a lot of these bamboo stars with a group, using a special jig.
