The Concept
Aesthetic, emotional, and empathetic selection are applied to a derivative of Karl Sims' Evolved Virtual Creatures.The resulting Creatures can be beautiful or strange, and provoke strong reactions in human observers.It may be possible to evolve virtual pets to which humans can form strong emotional bonds.

Sims’ Automated Evolution
Karl Sims used a GA to automate evolutionWith selection for:
Swimming speedCrawling/walking speedJumping heightAbility to follow

Sims’ Co-evolution
Karl Sims used GA selection for possession of a blockto create a co-evolutionary scenario

Ray’s Co-evolution
Rather than using GA selection for competitionI will evolve my creatures to loveBy selecting for:
Moving towards one anotherMaximum surface contactContinued relative movement while in contact
