  Thanks to /u/thomasahle for encouraging me to implement axial coordinates, which made it a lot easier. Also thought of a better way to parse the input in one go. And this allowed me to tighten up the grid dimensions. Runs in under a second on a very old laptop, half of which is because of the scipy import ... https://github.com/ednl/aoc2020/blob/main/day24alt2.py

  I'm also proud that to speed up my thinking through this grid, I literally downloaded the top image on the wikipedia article and rotated it 90 degrees. I knew conceptually that the grid he described was the equivalent to what I was looking at, but thinking through the deltas degrees off was hard, so I made it easier, and checked it in for kicks https://github.com/jackowayed/advent2020/blob/main/24/1920px-Tiling_6_simple.svg.png

  This was a satisfying one. I love working with hex grids. I used the similar 3-axis hex representation as day 11, 2017 (but rotated by 90 degrees), and the similar unbounded game of life pattern seen on day 17, 2020 and exactly a year ago on day 24 2019.
