Finally! I found that screensaver. I've been meaning to recreate it as a learning exercise. I once observed a mass extinction on this screensaver. A very aggressive carnivore (meaning it survived by eating other organisms in the sim), reproduced like crazy, used up all the resources and the died out itself. I only ever observed this once, despite watching the screensaver quite a bit.
