Eden – an evolutionary sonic ecosystem

Eden is an interactive, self-generating, artificial ecosystem. A cellular world is populated by collections of evolving virtual creatures. These creatures move about their environment, making and listening to sounds, foraging for food, encountering predators and possibly mating with each other. Over time, creatures evolve to fit their landscape. Eden has four seasons per year and each year lasts 600 Eden days. One Eden year passes by in about fifteen minutes of real time. A simple physics dictates only three basic types of matter in the Eden world: rocks, biomass and sonic creatures.
