Horse and cart

Interactions

Click the horse: it moves up into a trot with a moment of suspension, holds it for a few seconds, then comes back to a walk
Click the driver: he flicks the reins (the horse's ears go back and it steps on, the cart lags on its spring) and tips his cap
Click the cart: a wheel drops into a pothole; the churns jump and clatter, the driver bounces on his seat
Move the pointer: wind in the mane, the tail, the grass, the cow parsley, the hedge tops and the oaks
