Applying mathematics to Escher's Print Gallery

"This project aims to visualize the mathematical structure behind Escher's Print Gallery. This mathematical structure answers some questions about Escher's picture, such as: "what's in the blurry white hole in the middle?" By a five step process a wide variety of different pictures have been made, such as a straight picture, and a picture twisting the other way."

This is amazing stuff! Don't miss the animated zooms...
