I'm working at a bronze foundry where we recently got a CNC router. We have been messing with the software and hardware for a while and just made this puppy. He is about 4 feet tall and weighs over 150 lbs.
It was designed using a combonation of Silo and Zbrush.
We rigged it up with a garden sprinkler that pops out of the top of his head when it is on We call it The Gardener.
