I ran a Christmas workshop with a colleague for math education students at the university this evening. We made wire beaded stars, origami stars, paper snowflakes with 5-fold symmetry, and trihexaflexagons and hexahexaflexagons.
Glogg and pepperkake were served, and we had a guitarist come and play a Christmas song. About 30 people attended. It was an exciting evening and a lot of fun!
