This is quite a tricky photo. I held my webcam in front of the screen, and it generated such an image. You can see the point of infinity in the photograph. The same phenomena can be observed if two huge glasses are kept facing each other and parallel to each other. The light keeps on getting reflected from each glass and if you put your head in between them, you can see the +infinity and -infinity on either sides. Some people don�t understand this phenomena and consider it quite enigmatic.
