Sure, you can get much nicer plots easily with e.g. -
SetOptions[ArrayPlot, ColorFunction -> (If[# == 0, GrayLevel, Hue[#]] &), ColorFunctionScaling -> True, Mesh -> True];
Then you can make tables of plots for different values of prob, different widths, different numbers of steps, different numbers of starting particles on the left or in the center or distributed randomly, different periodic or random placements of ratchet locations, etc. It forms a whole little NKS system.
Lots of ratchets tend to "sort" everything to the right, ending in a one per location ordered stack or a cloud sloshed up on the right edge depending on the field value and number of particles involved. Few leave diffusion, which can be turned into a current by tuning the probability. You can dial in anything in between diffusion, current like flow, and one by one deterministic "sorting", for some set of parameter values.
