Clouds, water ripples, landscapes - they all have one thing in common:
they are fractal by nature. So to approximate them, some kind of fractal
noise tends to be the best method. The granite pattern is fractal noise,
iirc so is wrinkles. You can also create fractal noise by averaging
together several differently-scaled bozo patterns.
I myself like to use the latter, since this gives the most control over
the pattern. I believe you could get something like the example pattern
with this method. It won't be easy, no. But getting good results is
seldom easy.
