What you see isn’t always what you get!
  Since ancient times, humans have known that immediate perception is not a reading of physical reality. Vision is the most creative act that a human being is capable of. Seeing is depicting the world on the living canvas of our mind. As we depict well only what we really know, our mind is both the canvas and the artist. In this creative process, the eyes represent nothing other than a medium with which our mind interprets and reconstructs our near environment. Some illusions teach us to doubt and to question the many appearances of the reality - they are a kind of school of life!
