For Pi Day 2022 I used the same method as William Shanks and we got π = 3.14159265358... you know, etc etc.
What's up with this strange number coincidence
We believe that the "there must exist a single-angle polyhedron for any angle θ with an algebraic sine" conjecture is true but don't have a nice proof. There seem to be all the required parts for the proof in papers by Sydler and Jessen, but it's not fully assembled.

With a trusted 3rd party, running Secret Santa is easy: The 3rd party labels each person 1,…,n, and then randomly chooses a derangement from among all possible derangements of n numbers. Person i will then give a gift to the number in position i of the derangement. The trusted 3rd party is responsible for keeping the derangement secure, and for telling each person whom to give a gift to. The question is: Is there an algorithm that would allow Secret Santa to be played without a trusted 3rd party?
CORRECTIONS - At 02:32 I said that the complex locations was scaled so the height of the frame equals 2. For the examples on screen, we also made the width 2 by stretching it. But for actual pixel image transofrmations we used a linear scale for everything that made the height 2.
Huge thanks to Ben Sparks (and their brother Tim) for making the site, collecting the data and sharing the story with me.
Thanks so much to Mark Brittenham and Susan Hermiller at University of Nebraska at Lincoln for talking me through it.
