The Museum of Contemporary Art in Antwerp, Belgium, exhibited Cloaca, a large machine designed by Belgian conceptual artist Wim Delvoye that mimics the human digestive process. Each day, the installation is fed human food prepared by a top chef, which passes through various pungent tanks filled with acids and enzymes, eventually producing something resembling human excrement. Delvoye is also known for producing a herd of tattooed pigs, which he displays live and also sells in stuffed and pigskin form.
