If by some wild chance you have not heard of him, Gary Larson is in my opinion one of the greatest cartoonists of all time -- if you haven't heard of him please look him up!! He wrote a strip called the "Far Side". Cows always figured prominently in these strips...
If he had ever written a strip entitled: "If Cows had Porn", this would have been it :-)
These cool sculptures were made of big rocks (the bodies) with added metal legs, heads, etc.
