a split-screen view of a harbor, with one side displaying a time-lapse of the sky and water, and the other side showing a dark, static view of the same scene, creating a contrast between day and night. Across the loop, the time-lapse side shows the water receding and then returning, revealing and then covering the muddy bottom of the harbor, while the sky changes from bright blue to cloudy and back, and the dark side remains unchanged.
