Belgian neo-conceptual artist Wim Delvoye is known for creating shocking work.
His most famous work, Cloaca, is a digestive machine that turns food into faeces. Delvoye spent eight years working on the project, consulting with experts in fields ranging from plumbing to gastroenterology.
The artist sells the realistically smelling output in glass jars. The mechanical digestive tract has been reinvented in numerous Cloaca remakes. Delvoye was reportedly motivated by the notion that everything is pointless and nothing could be more useless than a machine to turn food into waste.
