This creepy guy is made out of decommissioned nuclear weapons parts. Artist Tony Price (1937-2000) discovered the Zia Salvage Yard at the Los Alamos Nuclear Laboratory and used the debris in his art. The one above is my favorite, and not just because it's called "First Mutant Man Born Without An Asshole." More of Price's nuke sculptures after the jump.
Fellow science artist George Gessert had also suggested creating art using nuclear weapons salvage, before he changed course and became a genetic artist, playing on our newer fears. Images courtesy of Atomic Art.
