Indeed - I looked up "digital camouflage"  and "camouflage algorithm" and got a
lot of hits on Guy Cramer and HyperStealth.


My thought was to use crackle on top of crackle, although maybe what you might
try is using crackle as a base pigment to scan with eval_pigment(), and then
overlay a randomized / turbulent cells or other blocky pattern "on top" of that.

I didn't have time to code anything up, but I'd say it's something that would
need to be iterative, rather than a straight-through one-time function evaluated
based on <x, y>
