So how does it work?


Because the dinosaur has the features of a face when looking straight-on, the brain focuses on his stare. But in reality (as seen in the video), the face is actually concave and creates the illusion it is following your every move. 


If looked at closely, the eye to the viewer's right is actually placed further away and below the eye to the viewer's left. Since our brain wants to believe we are looking at a face, we follow the right eye, which in turn follows the viewer. 


To sum it up, our faces are molded outward (convex) and that is how we are geared to perceive living beings. Even though the dinosaur's "face" is folded inward (concave), our brain won't let us see that because we are trained to do otherwise.
