The Bent Photograph

What if you could grab onto a photograph and stretch it apart, bend and twist it, as if it was made of metal. The idea seemed simple in my mind, but the process was quite involved. I basically cut an image in half, selected one column of pixels, then duplicated and rotated that around to make a complete circle. Then I cut the circle in half and brought the image back in. Now we have a sunset that is bowed.
