OK, one more thing; I got better results with the following texture block,
which removes the randomness of the whole thing:

    average texture_map {
      #declare S=seed(12465);
      #declare numiters = 255;
      #declare ix=0;
      #while (ix<pow(numiters,1/3)-1)
       #declare iy=0;
       #while (iy<pow(numiters,1/3)-1)
        #declare iz=0;
        #while (iz<pow(numiters,1/3)-1)
          [1
            pigment {color rgb 0}
            finish {diffuse 0 specular 0 ambient 0 reflection .8}
            normal {bumps .1 scale <.001,.001,.001>
                    translate <.002*ix,.002*iy,.002*iz>}
          ]
          #declare iz=iz+1;
        #end
         #declare iy=iy+1;
  #end
         #declare ix=ix+1;
      #end
    }
  }
