Taken in the Seattle-Tacoma Airport.
Why do I torture myself like this? This picture is made up of 28 layers, and while it stitched together pretty quickly, it took hours to retouch. You'd be suprised how hard it is to get an airport full of people to just hold still for a few minutes. It's so tempting just to cut the resolution in quarter so you can't see the stitching artifacts, but it feels like a sin to throw away that detail.
