"A History of the Sky reveals the rhythms of weather, the lengthening and shortening of days, and other atmospheric events on an immediate aesthetic level: the clouds, fog, wind, and rain form a rich visual texture, and sunrises and sunsets cascade across the screen. 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. Each day's images are assembled into a time-lapse movie. The final piece will consist of a large mosaic of 365 movies, each representing one day of the year, arranged in order by date. The days all play back in parallel, so that at any given moment, one is looking at the same time of day across all of the days."
