optical illusion

Some people have the uncanny ability to see the world from a perspective different from the rest of us. That perspective allows them to create optical illusions that fool us into thinking they're real.

Talk about an incredible mind trick. This T-Rex seems to turn it's head and follow you around the room. What's even more amazing is the way this optical illusion is created.

An optical illusion happens when the your eyes gather information that, when processed by the brain, differs from the true physical measurements or properties of the object you are seeing. This fun test shows how susceptible you are to optical illusions.
