Making RD patterns that tile like wallpaper is easy – apply periodic boundary conditions (PBCs, https://en.wikipedia.org/wiki/Periodic_boundary_conditions) when solving the PDEs.
PBCs are like the old-school Pac-Man arcade game: crossing the left side of the "screen" warps you to the right side, and ditto for top/bottom.

More interesting RD tilings are possible. Recently, Vladimir Bulatov has been making some really cool patterns with his SymSim software – check it out at https://symmhub.github.io/SymmHub/apps/symsim/gray_scott/index.html.
