Happy First of December!

Throughout the month, Hannah Fry & I will be tweeting out Christmathsy bits and pieces, one a day, advent calendar style… Assuming we don’t run out of ideas, which is certainly possible (What do you mean we should have thought this through beforehand?).

First up, a competition!

The stellated dodecahedron bauble done. I learned a lot about myself in making this. Mainly that I have a lot less patience than I thought.. pic.twitter.com/z71a1ufdhJ
