I saw a video quite a few years ago where they dump some ants on a platform, with a string leading to another platform with an area that (apparently) seemed like a decent home. (the below is according to my fallible memories) One ant wandered to the good area and checked it all out. She then marched back to the others, and bodily lifted another and took her to the good area. They both inspected the area and each repeated the trek to pull in another ant. This continued until "enough" ants were in the new area and they shifted into "build a nest" mode. It felt very oversimplified for TV viewers, but nonetheless was fascinating - a breakdown of just HOW some simple models can lead to more complex emergent behavior. I just tried to find this video without success (on the bright side, there are a ton of OTHER fascinating ant videos out there)
