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).

Lotus Artificial Life's Java cellular automata substrate capable of supporting evolving, self-reproducing organisms which are capable of universal computation.

Gene Pool is an artificial life simulation where populations of physics-based organisms evolve over time.

An imaginary gene pool, a primordial puddle of genetic surprises. Free download; Windows.

Freeware artificial life program designed for Windows. 2-dimensional evolutionary world with simulated neurons.

Java application simulates creature behaviours and movement. Available for free download, including source code, and a paper on Artificial Life.

Agents evolve to stay on the screen.

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?

Predators is an open-ended play-by-e-mail game. The game is an abstract simulation of animal species evolution.

Designed for people of all ages, the FishTank offers firsthand experiences in creating artificial life forms and reveals how simple behavioral rules can produce complex and surprising results.

Features three Java artificial life experiments.

An experiment in artificial life, and a game as well, where players create new animals to struggle and survive.

A networked, self-generating artificial ecosystem by John McCormack. A CD-ROM version for Macintosh and Windows is available for on-line purchase.

A project being developed by David Stern at Cambridge university. Available in stand alone or '@home' flavours.

Implements an artificial-life environment based on - and compatible with - Tierra, Tom Ray's well-known project, which displays open-ended evolution using a world of assembly-language creatures running on simulated parallel processors.

Simple world with automata that act to form complex systems. Implimented on the Macintosh.

A VB based simulator of food-gathering behavior of ant colonies. Executable and VB source code are available.

A model of human brain function designed by a neuroscientist at UCSD. The VIM is used to drive 3D characters who live in virtual worlds and can express emotion and creativity.

Highlights the Pandamat artificial intelligence system.

Modeling software, theory, and applications. Instream flow model for trout. Salmon out-migration survival simulator.
