Optical illusions are meant to mess with your mind. They’ll make you go cross-eyed in no time. There’s usually a very simple explanation for what’s going on in an illusion, but I still can’t wrap my head around what’s happening most of the time.

Here are a few animated illusions that you might have a hard time comprehending. I know I did.
