Over the past year I have invested a lot of time and effort creating tessellation patterns to be used for creating mazes. Five maze books are completely based on these patterns and four others used them in varying degrees. Because there are people who like tessellations but have no interest in mazes, an attempt to re-purpose the results of this effort seemed to me to be a reasonable use of time.
One attempt to reuse the patterns resulted in two coloring books, The Tessellating Alphabet Coloring Book, discussed here, and A Tessellating Coloring Book. Despite what its cover might suggests, the patterns it contains are varied and mostly derived from Tantalizing Tessellating Mazes and More Tessellating Mazes.
A second way of utilizing these tessellation patterns is to make typefaces from them. The Tescellations fonts are discussed here. A second set of two fonts, the TessieDingies package, has recently been released on myfonts.com. One font is devoted to patterns that are abstract.
