This is the famous Schelling's Segregation model. It shows how, with interacting agents, the aggregate result can be unexpected given the properties of the elements that compose the system.
Two kind of agents: a (blue) and b (cyan). When you setup the agents are deployed randomly in the space. The generic agent is happy (and doesn't move) if more than one half of his neighboors are of the same kind, and is unhappy (and moves) if less than one half of his neighboors are of the same kind. When you run the model the agents will move until all agents are happy. Each movment have a chain effect on the neighborhood the agent is leaving and on the neighborhood the agent is joining.
Change the number of ocuppied places, and the rate of neighbors of the same kind the agents prefers
