"Tessellations here mean designs featuring animals, birds, etc, which can fill the page, without gaps or over-lapping, to form a pattern that completely fills a space. It's the simplest kind of jigsaw puzzle: all the pieces look alike! You can see example tessellations in the top right corner of this website. The example changes each time you move to a new page.
On these pages, you will find information about all aspects of tessellations, from their history and development to complete galleries of examples by school students, guest artists, the webmasters Seth and David, and of course M. C. Escher, the pioneer of the art. Also included are extensive workshops showing how to design and produce your own. All are accessible from the orange navigation bar or from the site index -see below.
This site is a dedicated graphics site and not focused on the math. As M. C. Escher said, "Mathematicians go to the garden gate but they never venture through to appreciate the delights within." To use another metaphor, you're missing the fun if you use a microscope to enjoy a merry-go-round.
If, as a result of your visit, you venture through that garden gate, please send us your designs for inclusion in the guest gallery.

Two original albums of photographs of paintings and furniture looted by the
Nazis were recently discovered. The albums have been in private hands since
the end of World War II and will be donated to the US National Archives in
Washington, D.C. These albums were created by a special Nazi task force
engaged in the theft of cultural treasures in occupied countries. In the
closing days of World War II, US soldiers entered Adolf Hitler's home in the
Bavarian Alps

"Teenangels are a group of thirteen to eighteen year old volunteers that have been specially trained in all aspects of online safety, privacy and security. After completion of the required training, the Teenangels run unique programs in schools to spread the word about responsible and safe surfing to other teens and younger kids, parents, and teachers.
They write columns for Web sites and become expert public speakers and researchers. They work with companies like Disney, Microsoft and AOL and are trained by law enforcement agencies; their tuition includes experience in making presentations to groups of students in schools and/or at community events.
Teenangels have even been to the House of Representatives in Washington D.C., for the WiredKids Summit, where they presented their research to a powerful and influential audience.
At the urging of our Teenangel volunteers, a special group of volunteers will be able to continue as Teenangels after they become eighteen years old and a new group of Tweenangels has been formed for those between seven and twelve years of age. "
"The exhibition draws from the individual accounts and oral histories collected by the Voices of Civil Rights project, a collaborative effort of AARP, the Leadership Conference on Civil Rights (LCCR) and the Library of Congress. Made possible by generous support from AARP, the exhibition celebrates the donation of these materials to the Library of Congress and links them to key collections in the Library.
