If you're using megapov, you could #declare a pigment to be used as a normal,
like so:

#Cracks=
 function{
  pigment{ spherical
   pigment_map{
    [0 rgb 1]
    [1 crackle color_map{[0 rgb 0][.5 rgb 1]}]
   }
  }
 }

#object{ Headstone pigment{rgb 1}normal{function Cracks} }

This should make the cracks start from a center point, and then become just flat
further out. Just a simple idea that can be expanded on.
