Master of the optical illusion, brusspup, has recently uploaded a new video featuring a dinosaur of the tiny-armed variety. Staring at you. Wherever you go. That's a pretty neat (creepy?) trick, no?
OK, so given the nature of this trick, you could use it for anything. Pictures of whales. Or Sealab. But the post in question used it for the first BioShock, and that's about the best use I can think of.
Think your eyes have no trouble detecting when an object changes color, size, or shape? This new illusion crafted by Harvard's Jordan W. Suchow and George A. Alvarez might just prove you wrong.
