impossible motion

Impossible motion is a seemingly gravity-defying illusion created by Kokichi Sugihara of the Meiji Institute for Advanced Study of Mathematical Sciences in Kawasaki, Japan. Suguihara's "impossible motion" illusion won the 2010 Best Illusion of the Year Contest, held in Naples, Florida. The illusion is dispelled with a change of perspective and arises from the fact that we assume, wrongly, that the supporting columns are vertical and that the longest one is in the center.
