Just added a post with some of the behind the scenes details and unused footage from this video on my Patreon: www.patreon.com/HenrySegerman

New dice from The Dice Lab (me and Robert Fathauer), which may (?) be useful if you regularly write equations. youtube.com/shorts/fgMox...

This image (made with Saul Schleimer) shows two different ways to approximate the Cannon-Thurston map associated to the figure-eight knot. Cannon-Thurston maps are space-filling curves, a bit like the Hilbert curve except that these fill a sphere rather than a square.

I added a second post on my new Patreon, about my plans for a three-dimensional expanding racks design based on the srs net (also known as the Laves graph). See www.patreon.com/posts/135832...

I never got around to posting this animation I made with Saul Schleimer.This animates successively better approximations to a space-filling curve. (Or rather, you can tile the plane with the shape, and that gives the approximation to the space-filling curve.)

I finally got around to setting up a Patreon! It's at patreon.com/HenrySegerman. 
The first post is about my plans for taking the expanding racks project (youtu.be/iWknov3Xpts) from two-dimensional to three-dimensional networks. 
If you’d like to support my work, please consider joining. Thanks!

Working on a few three-dimensional expanding rack mechanisms. This one is based on the NbO lattice.

Saul Schleimer and I got our code for generating Cannon-Thurston maps working with sagemath algebraic numbers. The old code used floating point numbers which would eventually lose precision and blow up. With algebraic numbers we can go as far as we want!

Here’s another clip from my video on expanding rack and pinion mechanisms - an expanding pythagorean triple triangle. There’s a reason why it’s easier to make this kind of triangle! Full video at

A bigger version of our Geared cube net, for an art exhibition "Intersections: Math, Art, Truth, Humanity", organized by the Seattle Universal Math Museum and Glen Whitney in Seattle. Joint work with Sabetta Matsumoto. (The smaller original version: youtu.be/T3CkqXycT9w)
