YouTube Channel brusspup posted this video of a circle illusion that has quickly gained attention on social media. Its recent popularity is likely due to the way in which the video forces viewers to look at such a simple figure and movement from a new perspective, rendering it an entirely different video. This illusion, originally created by Arthur Shapiro and Alex Rose-Henig, of American University, illustrates a concept proven by Persian astronomer Nasir al-Din Tusi, which dictates that, if perspective is changed, images moving in a circular pattern can be seen as moving along a linear path, and vice versa. The illusion has been named one of the best illusions of 2014 by Scientific American.
