Abbas Kiarostami's five-segment experiment in digital cinema is a work of simplicity. Its subject is nature itself. Waves break on the shore. A lone piece of driftwood moves back and forth. Strangers walk along the coastline. A dog plays by the sea. A flash of bright light. Then come the ducks, waddling in and out of the shot. Finally, a reflection on water of the moon at night as frogs make a racket in the background.
