Artificial Life has been called a study of "life as it could be". It is a field of research that investigates the synthesis of life in the wet lab, with computer and robotic hardware or through software. This talk explores some fundamental ideas from the field including the ideas of emergence, self-organisation and the simulation of biological phenomena. Various examples of animated software simulations including models of habitat production, disease transmission and virtual ecosystems are presented. The underlying ideas behind these software models are discussed.
