Many different models of boids have been implemented. Craig Reynold's model (above), which sticks to simple, non-realistic, abstract boids, was one of the first. Some people at Georgia Tech have used boids to model the movements of groups of bicyclists, as well as one-legged, hopping robots (below).
For a class project, this person simulated a duck pond using boids (below).
This company uses boid models to produce realistic animation sequences of crowd behavior, here is an attempt to replicate Reynold's results, and this woman created a fish schooling model that includes predators (below).
A scene in The Lion King involving a stampede of wildebeests was modeled using boid techniques (below).
Among other cool activities, the Virtual Whale Project has created a model of Pacific herring schooling using boids. The video below shows a simulated school of Pacific herring being attacked by two humpback whales.
Althought these models are aesthetically appealing and appear to quite accurately simulate real herd animal behavior, all boid-based models suffer from problems.
