Four Circles Optical Illusion
Strait Line Optical Illusion
We see the lines on this optical illusion move to the left and to the right. The reason this type of illusion works is because the lines are all the exact same size. The squares don't line up and the colors contrast to make force your eyes into thinking it's moving.
Circle Optical Illusion
We think the circle in this optical illusion won't stop turning. It appears as if circles exist within circles in this image. When we look hard enough we can see the black and white on the outer corner of the squares, which gives the image its illusion of movement!

Dots, Dots and More Dots
Spinning Circle Optical Illusion
Swirling Optical Illusion
The colored dots in this image appear to pop out as us when we look at this image. It's caused by the sharp contrast between the black and the colored dots. Also, because of soft contrast between the gradient fill between the black circles and the white circles.
