Feed with click/drag. Calm mode removes predators. Go 3D moves the flock into a depth box — right-drag to orbit, scroll to zoom. Social HSL maps nearby boids, food, danger, and motion into hue/saturation/lightness.
Impersonate locks the camera to one boid and exposes its vital stats. Model: Wikipedia.
