A flattering flag is what you see when you see this image but one thing is to be noticed and that is the image as a whole is static.So this is what we call an optical illusion

Image Creator – Akiyoshi Kitaoka

Look at the center point of this image and you will observe that this image become in motion.Though this is a static image but on focusing at the center you will see it in motion

These rings are moving but the total picture is static,This is what we call a moving illusion

Wonder how this is possible..see closely you will see it moving in anticlockwise direction

Do you see the diamond shapes more prominent or the circles ? If you continue to see this image for a long time you will be feeling like these circles are in motion and are coming out of the diamond shape

Again coming to moving illusions, if you see these circles then they are moving clockwise and anticlockwise depending on there positions.

How do you suppose these pieces are going to join with each other in this illusion?

The Half round Object Appear To Split from one side and then join from the other.

You perceive a 3d sphere even though there are no edges.
