Thought-provoking. Thanks, Omie.

Anybody interested in emergent behavior should also check out Vehicles: Experiments in Synthetic Psychology by Valentino Braitenberg. Back in print after several years of being difficult to find. There are some simulators linked from Wikipedia.

The Boids link starts Java, if that kills anyone else's systems.

I like flocking birds.

One can also check out using Processing for Simulation and Artificial Life, including this sweet example: Swarm Box 3.

Reynolds' biods are a classic work in the field of computer animation. His SIGGRAPH '87 paper is a great read. Nice to see this work is not forgotten.

I was expecting boids and was curious what someone would want to model about them emerging from hiding places. The java critters were quite a surprise.

Flocking awesome.

I'd just like to point out Swarm was written by Metafilter's own nelson and a bunch of other, much smarter people. There's a lot better, more recent agent based simulation toolkits out there these days. Although Swarm is interesting as a historical footnote for being one of the very few non-NeXT based Objective C products out there.

I've still never seen something as cool as Karl Sims' locomotion evolution experiments. That work is 15 years old now; why don't we have videogames doing this in realtime?

The Breve simulation environment has some nice flocking variations, a Brietenburg machine you can mess around with, and some Karl Sim-ish stuff as well. Also, I misread the first link as "Photographs of fucking birds by Richard Barnes."

I have wanted for some time to apply Boids to the classroom. You know, give a few simple procedures to students and watch the cognitive flocking emerge. Still haven't quite figured it out, though.
