404 John Holland's ECHO - Echo is a simulation tool developed to investigate mechanisms which regulate diversity and information-processing in systems comprised of many interacting adaptive agents, or complex adaptive systems (CAS).

JuhasWorld - JuhasWorld: Yes it's alive! You have to see this applet to believe it. Just let those actors evolve for a few generations and they suddenly seem quite clever indeed. Wait a few more generations and you will be completely hooked: How good can they get?
