Non-Platonism can be found in many systems

Gray-Scott reaction diffusion system (U-Skate World)

Non-Platonism with respect to spatial resolution in the "U-Skate World" region of the Gray-Scott reaction-diffusion system. Note that the step size has been modified to meet the Courant-Friedrichs-Lewy condition. I constructed this glider from parts displayed in Robert Munafo's online gallery
