A Mind of Their Own : Software developers have created algorithms to emulate actors in CG movies. Most of the uses so far have been for orcs, ants and such in very large numbers. I remember reading about the initial use in TwoTowers where the developers gave random characteristics to the orcs and then ran the program. Most of the orcs ran into battle but some of them ran away. The dev guys said that they were surprised at how the characters interacted and couldn’t have predicted the emergent behavior of the group.
