Interactive Pictures 2

How to see Interactive Pictures? Look at the picture until it swims out of focus: it should be about ten centimetres away from your eyes. Now relax, so that you are looking through the picture, as it were, and after a while the image will double. Now slowly move the picture away from your eyes, at about one centimetre per second, without altering your focus, and the image will appear three-dimensional. Формат издания: 30 см х 23,5 см.
