Designer Revital Cohen imagines a future where life-support machines are replaced with life-support animals. In this scenario, a transgenic lamb is allowed to frolic in the fields by day. By night, the lamb is hooked up to a renal patient to filter his blood. The artist presents a mutually beneficial relationship: the human lives as a parasite, and the lamb lives to be a medical device, not Easter dinner. While it's an alien vision, it may be more humane than killing animals, engineered or not, for their spare parts.
