I just created this optical illusion using online gif animation creator. I combined two photos from Akiyoshi Kitaoka – the master of optical illusions, and fused them into one perpetual animation. If you stare at the animation below, you will notice it automatically switches among two different photos each 10 seconds. Your assignment is to stare at the center of it when the first picture loads (the one that is lighter at the left end, and darker at the right). Now concentrate and don’t move your head. After 10 seconds, new photo will appear – this time normal (not shaded) one. But wait! Your eyes got burned by the previous photo, so the new one will appear darker on the left side, while actually it is quite the same on both sides. I hope you understood what I was trying to explain! This is something new in the world of illusions. The best similarity I can think of, is Black and White Spanish castle illusion. Please spread this on Digg, Stumbleupon and other social websites, so we can show others this strange, new phenomenon!
