I asked the boys to flip through the book and pick out two shapes each that we could then order from Shapeways. Those shapes arrived today – yay!! I’ll do a more extensive project with these shapes later, but for today I just wanted to hear their reaction to seeing the shape and holding it in their hands.

My younger son happened to be home when the package arrived so he went first:

(1) A 120-Cell

The fun thing about this shape is that we’ve played with versions of the 120-Cell before:

This shape really caught my son’s attention in Segerman’s book – I’m glad he thought it was as cool in person as it was in pictures!

(3) Double Zarf

When my older son got home we unpacked his two shapes. I’d never heard of either shape before and am really excited to explore both of them. Both shapes come from the mathematical artist Bathsheba Grossman
