ROTFL

I assume Thorstens experience is writing POV-SDL is not sufficient to 
actually judge much about your code (although what he thinks might still 
be not suited for public citation).

What seems very inefficient to me is

   scale .001 warp{turbulence Terrain_Turb} scale 1000
   scale .01 warp{turbulence Terrain_Turb} scale 100
   scale .1 warp{turbulence Terrain_Turb} scale 10
   scale 10 warp{turbulence Terrain_Turb} scale .1
   scale 100 warp{turbulence Terrain_Turb} scale .01
   scale 1000 warp{turbulence Terrain_Turb} scale .001

since turbulence warps already introduce different scales of turbulence 
(how many is influenced by 'octaves').  So by having 6 warps with a 
scaling factor of 10 in between you overlay a lot of turbulences of 
equal scale which is unnecessary.
