I updated my website segerman.org to link to a few new things. There’s also a new page collecting together my virtual reality projects.

This seems like a hard problem: how do you make a physically manipulable (or at the very least a visual) representation of a puzzle whose moves are not associative?

We are hiring! The Department of Mathematics at Oklahoma State has two tenure track positions available. Let me know if you have any questions I might be able to answer, and also if you're planning to apply!

#introduction Hi, I've been using Google+ for having interesting discussions on mathematics and physics, particularly visualistations using 3D prints, animations. Since Google+ might be shutting down, I'm trying Mastodon.
I just salvaged all my old posts, and put them on a website:

Here is an example of graphics I do:

Working on the video for our extensor™ construction kit - accidentally producing music! MathMechs.com

Our extensor™ construction kit is now available to purchase from mathartfun.com/Polydron.html!

This animation shows one of the key principles of the extensor system: the extending motion can “turn corners” to make larger expanding structures.

There! This is a 'proper' Delaunay Triangulation and Voronoi Diagram. I did mess up in a few places with the lines for the Voronoi part though, I was still freehanding it and not using pencil guidelines XD

Our extensors mechanism construction kit is almost ready to ship! It will be available from mathartfun.com. This animation shows one of the basic principles - you can "unwrap" a standard scissor linkage around its axis of symmetry to make "branched" scissor linkages.

Animated version of my Geared Jitterbug (joint work with @sabetta) I learned how to make this kind of animation in Rhino/Grasshopper at Construct3d conference over the weekend, with some help from Edmund Harriss.

Finally got around to making Edmund Harriss' beautiful Curvahedra "Taurus"! Lots more cool designs at curvahedra.com.

if you're having trouble visualizing the recursive centaur i've made this helpful reference
