Police Detective Thorn (Charlton Heston): Soon they'll be breeding us like cattle! You've got to warn everyone and tell them! Soylent green is made of people! You've got to tell them! Soylent green is people!
Soylent Green 1: Mother and Soylent Green 2: Father are portraits of my mother and father. Soylent Green answers the age old question: what should we do with old people. Answer: eat them. Participants place their hand under the portrait to automatically dispense a squirt of Soylent Green syrup: a delicious thick substance made from my parents. Which do you think tastes better: Mom or Dad?
The Soylent Green portraits incorporate welded steel construction, a back-lit 35mm slide magnified by a fresnel lens, and a surplus automatic liquid soap dispenser.
