Herding Behavior

(via dailyspeculations) Vinh Tu writes:
Virtual birds form flocks, when each bird individually follows three rules:
1. Separation: steer to avoid crowding local flockmates.
2. Alignment: steer towards the average heading of local flockmates.
3. Cohesion: steer to move toward the average position of local flockmates
