In case you are still trying to find a present for yourself or a loved one who would like to hear more about what we mathematicians do and how so.... I can only recommend Bessis' book Mathematica. What a wonderful read. I could highlight every other sentence.

Over the course of 2022-23, I accumulated several dozen 3D-printed (selective laser sintered nylon) prototypes for jewelry. Here they are as ornaments for a holiday tree in anticipation of the solstice.

Looking for an *L.A. based* artist who (against all odds) has time for a poster gig before the end of the year.

It's for a science + art event.

We can offer $500 for the gig.

Dreadfully sorry about the timeline. Link a portfolio if you're interested, I'll delete this post when we found someone.
