This metal sculptures of ant colonie is work of Anthill Art and they is selling it on eBay. It is made by pouring molten aluminum directly into an ant colony.
“I make casts of ant colonies using molten aluminum to fill the tunnels and chambers of the nest. The result is an amazing sculpture showing the intricate detail of the nest architecture. The cast is then mounted for display on a wood base. Each display has a stainless steel plaque mounted on it with information on the cast and a unique cast number.”
