Ambiguous Images.

Hidden Circles This image, resembling a wooden door or something, contains sixteen perfect circles. Stare at the white x in the middle for a while, and they will suddenly pop out. The first time I read the description of the illusion I couldn't believe it. Perfect circles in a picture with only straight lines ? But it's true, see for yourself.  The statue on the left of the painting is obvious. But there is also another person playing music. Where is he, and what musical instrument is he playing ? A  Saxophone player in front of the right piller. A peaceful scene, reflecting rocks in a quiet lake. There are some people here, can you find them ?  Tilt ur head to the left, u can see a woman and a praying child. Try to find fifteen wolves.  A whole zoo of animals is used to assemble the portrait of a man. Find all 28 animals !  The face of a soldier and a man that is bending over.  Spirit of the Woods landscape and the face of a bearded man.  A very popular variant is the skull theme, like the classic on the right : All is vanity. This lady is looking Death in the eyes. Afterimage Keep staring at the white dot for thirty seconds, then stare at a white wall. What do you see ?
