Escher

I'll be giving a talk this spring titled "Infinite Possibility: The Importance of Mathematical Play." One of my three topics will be M. C. Escher's work with tessellations. I was sharing about this with a friend today and was surprised to learn that Escher is not universally known. His work has been a part of my life so long I thought everyone was familiar with it, so I decided to post a few of my favorites of his work - each having some mathematical aspect to it.
