Dr. Angry and Mr. Smile Optical Illusion
Dr. Angry and Mr. Smile Optical Illusion: The face on the left appears angry the one on the left is calm and happy.
What to do: Slowly move away from the computer screen and you should see the faces switch sides. Everyone will get it at a different distance so move back slowly.
Each face is a combination of the two faces the fine detail is what you see up close, when you move away you loose the detail and the raw shapes come out (happy fine detail, angry rough detail) This is based on work by Dr Aude Oliva and Dr Philippe Schyns You can read the original paper here.
