Looking through my scribbles in the margins of Herd, I came across a note about 'boids'.
Boids are CG flocking creatures created by programmer Craig Reynolds. The simulation designed a realistic flock of 3D birds, based on three simple behaviors: separation, alignment and cohesion.
We're reminded of the role these ideas play within a healthy organization, and the fact that a few 'true' principles can drive massively complex, self organizing group behaviors.
