Take a good look - what do you see? Close up it is clearly a faintly phantom-like image of Albert Einstein. Now step back 5 meters from the screen and take another look. Notice anything different?It's not just a crafty illusion. This sort of image is being used as a tool to understand better how our brains process visual scenes. On the practical side, some companies are interested in using them to conceal information from unintended observers - or to create printed advertising that morphs before your eyes!
