   Thanks... perhaps too fluffy, tough.

  Well, it's nothing fancy, just the average pattern. The real trick is
that the averaged blobs are concentric (with diminishing radius and the
same threshold):


   interior{
     media{
       method 3 intervals 1 samples Cloud_Samples
       scattering{2,.01}
       absorption .005
       density{
         average
         density_map{
           [1
             object{
               cloud_a
               color rgb 0
               color rgb .25
             }
             warp{turbulence .5}
             scale 2 warp{turbulence .67} scale 1/2
             scale 4 warp{turbulence 1} scale 1/4
           ]
           [1
             object{
               cloud_b
               color rgb 0
               color rgb .5
             }
             warp{turbulence .5}
             scale 2 warp{turbulence .67} scale 1/2
           ]
           [1
             object{
               cloud_c
               color rgb 0
               color rgb .75
             }
             warp{turbulence .5}
           ]
           [1
             object{
               cloud_d
               color rgb 0
               color rgb 1
             }
             warp{turbulence .5}
           ]
         }
       }
     }
   }
