Looking out from his window, photographer Eirik Solheim snapped an image of the same spot every hour for an entire year in 2010. He then cherry picked 3,888 of the best images and stitched them (with help from his readers) from left to right in chronological order. Each line is a different image and the end result is the interesting shot you see above.
