The internet was exploded by an optical illusion posted on Twitter by Japanese user @jagarikin, who specializes in such things.
In the GIF (looped short video), dubbed “Super illusion brothers”, the little men climb the escalator stairs and jump down. At least it seems so at first glance. In fact, the figures do not move, and the picture does not change. The illusion of movement is created by a change in color.
“If a bright point appears at one position and then reappears at a position shifted to the right, we tend to see a single object moving from left to right. This is the basic effect that underlies the smooth movements that we see in films and animation, “- quotes the words of Stanford University's The Sun.
