This optical illusion requires you to watch amazing video I have added at the bottom of this article. The Hollow Face Illusion is probably one of the most amazing optical illusions I have come across. Grand Illusions has commissioned this particular version of the Hollow Face Illusion. The original head of Albert Einstein was created by the sculptor Bryan Parkes and the manufacturing process was managed by David Burder. This is a 1.5 times life size version of Albert Einstein’s face, since the illusion works best when the head is slightly larger than life size.
