1. Aesthetically Evolved Virtual Pets Tom Ray Zoology, University of Oklahoma ATR Human Information Processing Research Laboratories, Kyoto

2. The Concept Aesthetic, emotional, and empathetic selection are applied to a derivative of Karl Sims' Evolved Virtual Creatures.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.

10. Sims’ Automated Evolution Karl Sims used a GA to automate evolution With selection for: Swimming speed Crawling/walking speed Jumping height Ability to follow

14. Sims’ Co-evolution Karl Sims used GA selection for possession of a block to create a co-evolutionary scenario

20. Ray’s Co-evolution Rather than using GA selection for competition I will evolve my creatures to love By selecting for: Moving towards one another Maximum surface contact Continued relative movement while in contact
