Day 23 was a twist on the classic Towers of Hanoi puzzle.
We have to stack like objects with each other, with restrictions on where and how we can move them.
I didn’t finish Advent of Code 2021 “during” advent; with a lot going on that year, I ran out of steam. I did go back and finish the puzzles later (in April), including producing this visualization.
Suffice to say, I did not reach the leaderboard for day 23.
Visualization
I put a lot into this visualization. We visualize both the process of searching for available moves, and in addition we animate the actual movement. I find the result to be quite visually pleasing and engaging.
