Its interesting how the brain understands or preceives pictures or objects. The brain automatically uses it's sensory to adapt the information. The eye's retna has a down-up and up-down vision. The retna preceives what it knows or should be seen. Perceptions must work fast on visuals, since we take in so much information at a time. If it were to work slow then a everyday task would be a very long process. Sometimes the brain also creates shapes that do not even exists.
