I have to dig up my old Geomorph code (2004-2005) in which I used
patterns (including crackle) in different functions to build isosurface
landscapes. It might inspire...

I fully agree.

Interesting result indeed. The "cells" are not looking "natural" enough
to my taste, but with enough tweaking...
It shows, imo, how we have to be careful with the amount of turbulence.
