The other fun thing with WFC is that you can wrap the constraints on the edges (ex. matching the right edge of the rightmost tiles to the left edge of the leftmost tiles), which allows you to easily make tiling patterns. You can also start matching tiles and edges for more than just colours... for example, you can have 3-dimensional tiles, or you can even match edges of tiles using time as a dimension, like I did here: https://twitter.com/MattRix/status/979020989181890560 https://twitter.com/MattRix/status/979020989181890560
