Filled truchet tiles, now animated thanks to shaving by @donbright

u/donbright

the thing that strikes me is the black and white balls never move, only their connections.... but it looks like the whole plane is aliv
u/magna

@donbright To achieve that: Starting with a single tile, every other tile is flipped on the X axis. And then to flip a tile, I need to both invert the tile's pixels and also to flip it on the Y axis. Lots of XOR was needed :)
