Every spring the folders of each town lay thousands of sleeping paper birds on their great sculpture. You are the spring wind that wakes them.
Tap a bird: if nothing is in its way, it flies off to join the great flock. If a bird is in its way, it bumps and settles back.
Birds of the same colour facing the same way on one line are a flock: tap one and the whole flock flies, as one flight.
A bird of another colour between them splits the flock: free it first and the flock joins up. Clear the sculpture in the fewest flights for three stars.
Turn the sculpture with a finger: birds sit all round it.
