"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. Link to us! To put a button that links to us on your website, if you're comfortable with HTML then just copy the text below, change the text to suit your feelings, and add it to your website."

"In 1481 the monks of San Donato a Scopeto near Florence commissioned Leonardo da Vinci to paint an altar-piece celebrating the Adoration of the Magi. In one of the preparatory drawings, Leonardo drew with meticulous accuracy a refined perspective grid in order to place the architectural structures, the human figures, and the animals in a realistically proportioned way.This precious study, kept in the Uffizi Gallery in Florence, is shown for the first time ever in the United States on Finmeccanica's initiative and because of the collaboration between the Uffizi Gallery and the Library of Congress."
