Well, this is sort of a sad example, but I created it when I realized that
by controlling the 4th dimension parameter with 3rd dimensional variables,
interesting effects could be created.

The code that created this image was

#declare mynoisegen = noise_generator {
 4
 match_second_derivatives off
}
#declare mynoisegenfunc = function {
 noise_generator{mynoisegen}
}
isosurface {
 function {sqrt(x*x+y*y+z*z)-1 +
mynoisegenfunc(x/.3,y/.3,z/.3,x*y*z/.027)*.25}
 ...
}

BTW: it won't be long before I release this patch, I think.

I don't follow the math entirely, but this is a neat image!

Looks like a little planet- a cross between Flintstones and Whoville!  Cool.

Cheers!
