     No probs, but just to clarify, it was my bad that I forgot to take the 
camera out of a 'non-hollow sphere' when it parsed over-night for ten hours, 
(I pasted a camera scene from another file, and didn't check).

     Frango's code is correct, and with a texture/pigment statement, it 
gives a 'pill'-like appearance:


  blob {
  threshold 0.5
  #declare Length = 0;
  #while ( Length >= -30 )
   #declare Scale = 2;
   #while ( Scale >= 0.25 )
         sphere { <0,0,0>, 20, 1 scale <1,1,0.9>

         texture{ pigment{ colour White}}

        translate <Length,0,0>
        scale Scale
      }
     #declare Scale = Scale - 0.1;
   #end
   #declare Length = Length - 0.25;
  #end
 }
