A video uploaded to the Internet on Monday showing an “amazing T-Rex illusion” has gone viral, achieving nearly 3.5-million YouTube views in the days since it was posted.
According to Slate, the “key to this whole thing is the way your brain sees perspective.”
“Your brain wants to interpret the dragon as a face, and faces are convex: The sides of the face curve away from you (when you look at someone’s face, their nose is closer to you than their ears),” a Slate post said. “But the dragon’s head is actually concave; the sides of the head curve toward you from the center.”
“This sets up a contradiction in your brain; the cues you get as you move around the dragon get mixed up, and you think it’s turning to follow you,” the online magazine explained.
Despite the scientific explanation, however, the illusion has succeeded in freaking out a number of individuals.
“My mind has been blown,” commented one person on YouTube.
“That’s mind bending,” wrote another.
