They are the same picture, with on of them rotated upside-down. Feel strange huh? BoingBoing says they are called Scheibe Illusion.


Mighty Optical Illusions has another example.

Actually something like this illusion can be done using paper money(only those with heads). Fold the head into 3 parts and see it from the top, then rotate it and see it upside-down. I know you won’t be understanding what I’m trying to say. Too bad, I have no camera to shot it down – in future, maybe.
