Escher documentary now online!

Achieving the Unachievable provides a glimpse into Escher's world through the hole in the middle of the lithograph "Print Gallery." Jean Bergeron tells the tale of Professor Hendrik Lenstra's mathematical realization of what "Print Gallery" should have been and a whole lot more about Escher. It's a fascinating must-watch for any Escher fan and it is available to stream or purchase (for those of us who have moved on from DVD's)
