You can definitely play with symmetry when laying out the tiles. Here's those same red plastic tiles from before, and again after re-arranging to make a composition with 90° rotational symmetry.
How many unique tile designs do you see here? (Hint, it's the same in both images.)

I had to write a homemade finite element method (FEM, https://en.wikipedia.org/wiki/Finite_element_method) solver to simulate the Gray-Scott model on this weirdo domain. FEM solvers tend to throw up their hands and quit when you point them at non-manifold geometry like the folded and glued square, but I hollered at mine until it started behaving.
