It's fun to sit down and draw what the board looks like when you cut and flatten the torus before you watch the video!<p>Bonus points if you hit upon the other 2D projection that is useful (I didn't)
Thanks for sharing!<p>Rotating the torus eventually hits singularities and I cannot continue the rotation. Maybe use a different mechanism for rotations that do not suffer from "gimbal lock"?<p>Would also be nice to rotate the torus along the circular axis. That is, rotate pieces/rows from inside the doughnut hole to the outside.
Shameless plug. If you're into chess-themed puzzles, you might like:

My favorite torus game is Tetris on a Torus<p><a href="https://www.benjoffe.com/code/games/torus/" rel="nofollow">https://www.benjoffe.com/code/games/torus/</a>
very neat. I'd say this is kinda on top of a torus, and more of a cylinder from the perspective of the Tetris pieces. not sure how you'd play on the surface of a torus, since you need to wrap around vertically too.
Took me a while to realize it was a 3D torus and I had to drag around to see the whole board lol<p>Maybe when the page loads the torus should rotate around a bit
looks like the white king/queen aren't on the right colors (queen goes on her color) - confused me a bit when trying to map the space to a 2d board
