An afterimage is an optical illusion that refers to an image continuing to appear in one's vision after the exposure to the original image has ceased.
Negative after-image induces the complementary color of the original image. (Positive afterimages, by contrast, appear the same color as the original image).
Stare at the center of these images (one at a time) for 30-60 seconds, and afterward switch your view to white surface area below.This can induce an afterimage of the of the complementary color (for example, the color red induces a cyan(greenish/bluish) afterimage). For a black-and-white picture,the afterimage is the opposite (negative) color to the original. If the afterimage starts to fade, blinking can make it to reappear.
True belief or self-illusion? - Depending on your own social-political belief, pick one of the following images and stare at the nose of the Ghost for 60 seconds, and afterward switch your view to white surface area below. This can induce an afterimage of your savior to appear. If the afterimage looks like a stranger, you need a second opinion. Stare at the Ghost again for 60 seconds, then close your eyes and tilt your head up. Keep your eyes closed, you will soon see a halo of light. Continue looking at the light and a longer-lasting and clearer afterimage of your savior should appear. A few Obama girls claim that they are able to visualize the "YES WE CAN" after-message as well. Those girls are true believers!

stare at this negative photo of her for a minute or so. Don’t forget to fixate the dots on her nose while you’re doing it. After some time, turn your eyes to a plain surface right next to the image. A “negative of a negative“, a proper image in full-color if you will, will then appear momentarily. The more you blink, the better afterimage effect you’ll experience!
This is a color photo followed by its black-and-white copy. If you stare at the dot of the color photo, you will see the complementary color appearing on the wall in black-and-white copy.
The motion aftereffect (MAE) is a visual illusion experienced after viewing a moving visual stimulus for a time (tens of milliseconds to minutes) with stationary eyes, and then fixating a stationary stimulus. The stationary stimulus appears to move in the opposite direction to the original (physically moving) stimulus. The motion aftereffect is believed to be the result of motion adaptation.
For example, if one looks at a waterfall for about a minute and then looks at the stationary rocks at the side of the waterfall, these rocks appear to be moving upwards slightly. The illusory upwards movement is the motion aftereffect. This particular motion aftereffect is also known as the waterfall illusion.
Another example can be seen when one looks at the center of a rotating spiral for several seconds. The spiral can exhibit outward or inward motion. When one then looks at any stationary pattern, it appears to be moving in the opposite direction. This form of the motion aftereffect is known as the spiral aftereffect.

What is Motion Aftereffect?
Motion after-effect occurs when you stare at something that is moving in a particular direction for at least 30-60 seconds. When you look away from the movement and look at a stationary scene it will appear to move in the opposite direction.
