Sheepdog and flock
Interactions
- Click the pasture: the collie gallops a wide outrun to that side of the flock, drops, then creeps in and drives the sheep away
- Click the fold gate: it swings open, the shepherd walks up and signals, the dog pens the flock; later they are let out again
- Click a sheep: it bleats with its head up and a jolt, and its neighbours look round
- Move the pointer: wind drifts the clouds and leans the grass and the hawthorn
