Okay, that's impressive. The legs attached to those feet appear to be standing reasonably straight, and the camera angle also appears to be approximately perpendicular to the floor. Even allowing for a certain amount of creative cropping -- and either holding the camera upside-down or flipping the picture afterward -- that combination of angles looks like it ought to be impossible. Certainly I can't do that, and I am not sure I could even have pulled that off when I was younger and somewhat more flexible (not to say skinnier) than I am nowadays.
