New 3D Print I'm really proud of this one as it was quite an effort. And it turned out so much better than I expected. The walls are thin enough to be slightly translucent, so it's lovely in certain lighting. It's also kind of pricey but there is no markup, so if you order one you will pay my cost. http://shpws.me/Pg8i To understand the shape, check out the following two Visual Insight posts by John Baez. https://blogs.ams.org/visualinsight/2014/08/01/733-honeycomb/ https://blogs.ams.org/visualinsight/2014/08/14/733-honeycomb-meets-plane-at-infinity/ Which one to tackle next? There are a ton of choices... https://en.wikipedia.org/wiki/Template:Regular_honeycomb_table http://shpws.me/Pg8i

A new batch of images for Wikipedia These are like the upper-half-space boundary images in Visualizing Hyperbolic Honeycombs , by Henry Segerman and myself, but shown in the Poincaré ball model. This album fills out a table of regular {p,3,q} honeycombs for Wikipedia. If you want to understand what these pictures represent, check out the paper! https://arxiv.org/abs/1511.02851 https://photos.app.goo.gl/aXmvsayuR1a5Hy5C3

Eclipse in Spherical Video Here are a couple spherical videos of our solar eclipse experience that capture environment changes and the incredible excitement everyone was feeling. It's really cool to hear the reactions to totality. Tiny Planet (about 4 min of video surrounding totality). https://youtu.be/bNzoaOKLSZY Spherical (about 15 minutes, with totality towards the end). https://youtu.be/CH7PX0ZQxuU https://youtu.be/bNzoaOKLSZY

I was able to attend the Illustrating Mathematics workshop at ICERM last year and thought it was fantastic! Now there is an opportunity for an entire semester of fun.
