A History of the Sky

(YouTube Link)

A History of the Sky is Ken Murphy's ongoing project to record time-lapse images of the sky. Each square in the video represents a day, and each day is in order:

This is a work in progress. Currently, an image of the sky is being captured every 10 seconds from a camera installed on the roof of the Exploratorium, on the edge of San Francisco Bay. The images collected over each 24-hour period are assembled into a 6 minute movie (at 24 frames/second).

The final piece will consist of a large projected grid of 365 movies, each representing one day of the year, and cycling in parallel through consecutive 24-hour periods. The viewer can stand back and observe the atmospheric phenomena of an entire year in just a few minutes, or approach the piece to focus on a particular day.

This will also be an active piece. The camera will continue to collect images and integrate them with the montage daily. The visualization will therefore vary from day to day, and will always display the most recent 365 days.
