Here’s an incredible optical illusion. You’ll need to wait few seconds before the .gif file fully loads, but when it does I promise you’ll love it! Once the animation has started, you’ll quickly notice how outer-rim dots begin shifting themselves up and down. But what is so cool here, is that this is actually an illusion! Our little dots haven’t changed their starting position one bit! The only thing changing here is their color; from white to black and vice-versa!
