Ken Murphy installed a camera on top of the Exploratorium in San Francisco and set it to take a picture every ten seconds for a year. A History of the Sky is those pictures as a series of time-lapse movies where each day is represented with a grid. So what you see 360 skies at once:
Time-lapse movies are compelling because they give us a glimpse of events that are continually occurring around us, but at a rate normally far too slow to for us to observe directly. A History of the Sky enables the viewer to appreciate 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.
Time-lapse: Yep, still fascinating.
