A nice video -click on the YouTube Icon at the bottom right of the video to be taken to the YouTube site to be viewed at a larger format.
From the creator's video description:
This is a year-long time-lapse study of the sky. A camera installed on the roof of the Exploratorium museum in San Francisco captured an image of the sky every 10 seconds. From these images, I created a mosaic of time-lapse movies, each showing a single day. The days are arranged in chronological order. My intent was to reveal the patterns of light and weather over the course of a year.
This video is designed to be viewed in a large format, so it's best viewed in full-screen mode at 1080p.
