That's brilliant! I don't know how I missed that in the documentation, (or
maybe I just never understood what it was trying to say).
What controls the pigment value selected for the cell? Is it just a random
number, or do proximate cells select from the same value range. I'm finding the
more variation with smaller ranges in my pigment_map, the less "clumpy" the
cells become, but does it follow the normal ramp_wave or is it just a linear
