San Francisco’s picturesque fogs form “The Unseen Sea” in Simon Christen’s timelapse. Viewed at the right speed, the motion of clouds becomes remarkably ocean-like, with standing waves and surges against the hillside like waves crashing on a beach. Clouds in air don’t have the same surface tension effects as water waves in air, but, for the most part, the physics of their motion is the same, which is why they look so alike.

Awesome one, but hey: are these tiny bright dots moving around drones?? ?

I think they’re just regular aircraft. Some of the patterns look a lot like airport approaches and take-offs.
