A stunning year-long timelapse:
The YouTube caption:
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 secobnds. 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.
