The Amazing Dots
Watch the X in the middle very closely. You should start to see a green dot that rotates around the circle - this dot is an illusion; then you should see see the purple dots disappear.... but they haven't really gone. It is an after image effect, sometimes called a 'negative retinal afterimage' - move your head slightly, and the dots will reappear... amazing or what?
Optical illusions
Head On Sand
A man lying on the sand with his head beside him in this illusionary image.
Rock Faces Illusion
Optical illusion of depressed faces in the rocks.
Cat Optical Illusion
Optical illusion of a mouse and a cat.
The Spinning Silhouette Optical Illusion
This is a very bizarre dancer optical illusion. At first glance the spinning lady appears to be circling in a clockwise motion. But if you look at the spinning dancer long enough - the lady will appear to change direction and start spinning counter-clockwise.
Mirage(ภาพลวงตา)
If you take a look at the following picture , let me tell you ... it is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it.... Weird
They look pretty normal, right? Now look at these
