But until I started this project, I don't think anyone was daft enough to make reaction-diffusion Truchet tiles that match up no matter how you reorient them.
The central trick is to solve the Gray-Scott PDEs on an unusual topological domain that collapses all of the edges into a single segment.

Here's what it looks like, starting with a square sheet (a). First, fold it into quarters (b), then fold diagonally to put all of the boundary edges on top of each other (c). Finally, glue all of the edges together (d).
