This applies for pigments, but not for use with heightfields and
isosurfaces.  Tony's idea was quite good for smoothing the pattern itself,
but in your case it does not help much because of the color_map.  

The following should look better, because the color_map is much
'smoother':

    dents
    colour_map {  
      [0.0 rgb 0.0]
      [0.3 rgb 0.1]
      [0.4 rgb 0.2]
      [0.6 rgb 0.7]
      [0.8 rgb 0.9]
      [1.0 rgb 1.0]      
    }

You can also try to specify a more detailed color_map using a #while loop
for example.
