Sign up on Patreon for the SUM xmas card! https://www.patreon.com/standupmaths If you want the physical card you need to be greater than or equal to "Statistically Significant".
Physical card deadline: end of 06 December 2022
Digital card deadline: end of 15 December 2022
(In both cases I’ll try to accommodate sign-ups after that but no promises).

Huge thanks to my Patreon supporters who funded so many sheets of mirror acrylic. I actually have a bunch left over. Support me and tell me what I should do with the rest of the mirrors. https://www.patreon.com/standupmaths
