Bedö also uses the ant metaphor to talk about the 'strong emergence' of overarching structures by locative mappings in seemingly ant-like behavior.

More specifically I find the second one very important: the notion of signal and the fact that it is communication. That's why I like this as a metaphor to play with for urban computing.

The examples of communication based on transforming avatars he gives are no exception : meaning rely on shared interpretation of the signs transmitted. - Stigmergic behaviors are used to solve complex problems.
