Three Spheres II (M.C. Escher)
"A child who looks into a mirror for the first time is surprised when he notices that the world behind the mirror, which looks so real, is actually intangible. However he soon ceases to consider this false reality as being strange. - In the course of time the surprise disappears, for a mirror is merely a tool used to help one see themselves, how other's see them."- MC. Escher
