An even checkerboard plot model dominates the green landscape during the rainy season, which becomes more austere after harvest.
The model can be visualised by considering relativistic random walks on a two-dimensional spacetime checkerboard.
As in the checkerboard example, the positive symbols are forced by the finite type rules to occur in rectangular patches.
Contrast values obtained from two subsequently displayed full-screen patterns may be different from the values evaluated from a checkerboard pattern with the same optical states.
