The idea behind the illusion is simple—as you follow the arrows, the circles appear to move in the same direction the arrows are pointing to. Also, the circles seem to expand and contract in size, when in reality, it’s nothing but a clever illusion.

“There are very thin rings on the outside and inside of the large rings, featuring the same blue and yellow colors,” a Reddit user under the nickname EverydayEnthusiast explained. “Those thin rings are manipulated in ways that, when compared to the large rotating rings, trick the brain to perceive it as movement or change in size. It’s a very good illusion! The arrows are there to either complement the effect or convince the viewer that the rings are moving/changing in size when you remove them.”
