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.
