Are you ready for a cool eye trick session? I’m sure you are, but be careful not to brain freeze…

Former NASA scientist Kurt Wenner came up with some street art that are some amazing 3D optical illusions. They look so real it is difficult to believe that they were painted. With a person standing next to one of them you would swear that the art next to them as real as they are. The man is a scientist as well as an artistic genius.
