What do you mean when you say you tried to do a centralized version of 
crackle, but it didn't do it? The cetralized crackle didn't form cracks, 
or you couldn't make a centralized crackle at all?

The reason why I ask is because I found the solution to making crackle 
with radiating lines yesterday. Actually, Alex Kruchikov found it first, 
but he took it futher to create his curles pattern (see Curly Patterns, 
povray.binary.scene-files 9/13/03). I haven't made really good erosion 
patterns with it yet; it's going to take some heavy-duty layered 
patterns to get what I want.

Here is the altered code if you are interested:

//The Code

#declare Spokes=
  function{
   pattern{radial frequency 4}
  }

#declare Cells=
  function{
   pattern{crackle form x*1 }
  }

#declare Starbursts=
  function{
    (
     sin(
      +Spokes(
       Cells(x,y,z)-Cells(x,y,z-.03),
       0,
       Cells(x,y,z)-Cells(x+.03,y,z)
      )*2*pi
     )
     +1)*(1/2)
   }

plane{y,0
  pigment{
   function{Starbursts(x,y,z)}
  }
}
