WATCH: MIND-BLOWING OPTICAL ILLUSION FUN WITH ROTATING CIRCLES AND ARROWS

This mesmerizing animated GIF is an excellent illustration of an optical illusion where our human cognitive system plays a trick on itself and see something that’s no really there. In this case directional arrows within two-color, spinning circles trick the mind into seeing directional shift in the position of the spinning circles up, down, left, right, outward and inward. It’s mind-blowing yet obvious, and helps explains some of the techniques sometimes used to create op-art. Happy Wednesday!
