Impressive! How did you tweak the wrinkles function to get those wide
coastal plains?

See you in Khyberspace!

1. Define a function{pigment{PATTERN turbulence FOO}}
2. Define a function{pigment{function}} based on 1 with a color map which sets
up a nonlinear relationship.
3. Declare a pigment{function}} based on 1, inserting whatever colors you like.
4. Declare an isosurface with function {y-function2} and pigment from 3.

Oh well, I'll just give away the kernel here:

#declare feestruct=
function{
pigment{
function{rawfee(x,y,z).grey}
color_map{
[0        color rgb 0.0]
[sandline color rgb 0.0]
[treeline color rgb 0.1]
[1        color rgb 1]
}

}
}

The image is very nice!
Btw, have you tried to approximate the contours with the hexagons of the
grid? Could also be interesting.

Hi, thanks!  Here is an update, this one based on dents.

Yes, eventually it would be cool to make the individual structures be merely a
collection of hexagons.  Haven't got there yet.

Based on dents ? It looks like crackle.
