Math and the Art of MC Escher is an educational site and is hosted by Saint Louis University. We do not require any financial donations.
Intellectual constributions however are always welcome.
We do thank the Escher Company for graciously allowing us to use Escher's work as illustrations for this site. The Math and Escher course relies heavily on the use of Escher's artwork as a motivating tool.
