Infinite Zoom Coast Illusion

Joseph Mohmed stumbled upon this awesome continuous animation. It works by the Droste Effect principals, and the illusion is almost identical to Escher’s window and Zoomquilt illusion. I was starring at this gif for almost five minutes, and couldn’t spot the photoshopped part. I know this was done by a computer, I just can’t seem to understand how. Can some of you see the manipulated part? Please comment.

If you like this kind of illusions, I believe you’ll have fun time checking Christopher Walken in space, Flying through city animation, Scary Spider illusions, as well as many others that can be found inside Animations category. Enjoy!
