The Remarkable Self-organization of Ants | Biomimicry |

"Give a colony of garden ants a week and a pile of dirt, and they'll transform it into an underground edifice about the height of a skyscraper in an ant-scaled city. Without a blueprint or a leader, thousands of insects moving specks of dirt create a complex, spongelike structure with parallel levels connected by a network of tunnels. [...] Knowing the rules behind ant-made structures could help scientists understand how other complex systems emerge in nature."
