'A History Of The Sky': Timelapse Shows The Sky Change Over A Year (VIDEO)

We humans love to witness change over time -- from bread rising to babies growing -- so good thing there are all these years-long timelapses that give it to us in a matter of seconds. The latest in this vein is a one-year-long time-lapse of the sky, aka "A History of the Sky." The artist, Ken Murphy, installed a camera on the roof of the Exploratorium museum in San Francisco, taking an image of the sky every 10 seconds. He let the images roll for a year (actually 360 days, he says, since "it's easier to make a nice rectangle") and compiled them all in one mosaic, with each box showing one day in the life of the sky. Murphy got his project funded on Kickstarter, with 52 pledges equaling $3,578.

So what's the takeaway here? The sky has a lot of different moods, and we like her in her purple mood best.
