Many years ago there was an image of an ice floe done by a height_field 
generated by a pigment map, and some time in the past maybe 2 or 3 years 
ago of a road using the same technique. I am trying this technique and 
it is failing miserably.

My memory tells me it's something like this:

pigment {
       spherical
       pigment_map {
         #for(I,0,255,1)
           [ I bozo
               scale 0.1
               color_map {
                 [ I/255  Green ]
                 [ I/255  Red   ]
               }
           ]
         #end
       }
     }

but all this gives me is a red object.

Can anyone find the originals?
