She also illustrates examples of semi-regular tessellations and ones that go on for ever. Tessellation Resources Professor Doris Schattschneider from Moravian College maintains two pages of on-line resources for those interested in learning more about tessellations. The first page is a list of resources mostly available in hard copy. The second page has listings of downloadable software for creating tessellations.
