“Animals Inside Out” is an exhibition of animal corpses that have been perfectly preserved with plastic polymers in a process called “plastination” (video). The exhibition is by plastination inventor Dr. Gunther von Hagen. Von Hagen is best known for his Body Worlds exhibitions of plastinated human cadavers. “Animals Inside Out” is on display at the Natural History Museum in London through September 16, 2012.
