Unfinished Test
This was a test model I messed around with one afternoon after seeing on frontline that how bees choose a new hive is an emergent phenomenon. The basic premise was that scout bees go out and look check out new hives. When they return, they do a little dance to tell the other bees how great the hive they found is. When other bees also try to report about the hives they saw, it's all about who has the most emphatic dance (they also try to disrupt the dance of one another). I thought it woud be cool to model this, but never quite finished it.
