Could you explain what's happening here, because I can't see what's so 
special about the image.

Just that no DF3 file was used.

Nice! How would it look with a black/white color_map and ambient 1?

Removing radiosity, single light source instead (irrelevant but for the
shadow on floor), diffuse 0 ambient 1

texture_map {
[ clock  pigment { rgb 0 } finish { ambient 1.0 diffuse 0.0 } ]
[ 1.0-clock  pigment { rgb 1 }  finish { ambient 1.0 diffuse 0.0 }]
}

 povray Fro.pov +KI0 +KF0.4 +KFI1 +KFF3 +FJ

The value 0 & 1 of the map are very seldom reached, so reducing the
range is also interesting.

The original object has a size of 60. The 3 objects were using proximity
with a radius of 1, 10 and 20. (from left to right)

It looks like your technique is going to be much simpler to use than the 
Proximity Macro which, by the way, was already a major and important 
achievement gladly acknowledged, thanks to Edouard Poor.
