"Rubin Vase. This is one of the most famous optical illusions that exists. There are two things that you can see in this image ... In black you can see two faces looking directly at one another. In white, you can see an interesting curved vase."
I know why this works!!! On the floor it has shadows and lights, and on the walls there are two lights. The floor has shadows on it where there shouldn't be because of the fact the other light is right next to it while both lights are on. -ZEE BADGER
