Mathartfun is a family owned and operated business located in Phoenix, Arizona. We first opened our virtual doors in October of 2000 as the online store for Tessellations, which has been serving parents, math teachers, and math lovers of all stripes since 1994.

Mathartfun offers secure online purchase of the full line of Tessellations product, as well as a wide variety of complimentary products personally selected by owner Robert Fathauer. Dr. Fathauer makes use of over twenty years of experience designing products, writing articles and books, creating mathematical art, and organizing exhibits of mathematical art to bring you a wide selection of unique products, many of which are hard to find or not even available anywhere else in the US.

The art of M.C. Escher has been Dr. Fathauer's biggest inspiration, and Mathartfun offers an extensive collection of licensed Escher products. Mathartfun is also the registration website for the Bridges Conference on connections between mathematics and the arts. We sell all of the proceedings, CD's, and art catalogs for past conferences.

In 2010, upon the retirement of Russell Jacobs, Tessellations acquired the titles of Jacobs Publishing. These books, including the popular "by Design" series, are featured on

In addition to our online presence, we occasionally sell at teacher and mathematics conferences. To find out about upcoming conference appearances, please "like" Tessellations on Facebook.
