Hi:
As I promised in class, during the Science lesson about the eye, here are some excercises about optical illusions. Enjoy!
Can you see the Mona Lisa?
Stare at the black point. You'll see all the colors fading out!
How about these circles? Are they moving too?
Keep staring at this picture for about 20 seconds and then look at a white surface (a wall or a big piece of paper). One of the very classic illusions. The best thing is ; the afterimage seems to be a sharper picture than the original
