I hope I understood just what you were saying about the noise3d. If
indeed I understood you correctly, you wanted a sphere that has a thick
center while remaining to have a gnarly outside, right?

I just blobbed together an average, but small sphere with a normal sized
one that has a lot of noise3d. I also fooled around with strength ratios
between the two objects. The "&(y+1)" is just a plane I intersected the
object with.

Code:

isosurface{

 function
  (
   (x^2+y^2+z^2+noise3d(x*8,y*8,z*8)*8)*
   (x^2+y^2+z^2+.5/100)
  )
 &(y+1)

 threshold 1 sign 1
