Over the past twenty years I have developed/created/found a lot of tessellations patterns as I have designed maze books, coloring books, an activity book, and a book about tessellations. A few years ago I decided to make a couple of typefaces from some of this material, but those typefaces were only outlines. This past year I again decided to try to use this material, which has since grown, in typefaces. After a dead end or two, I have mostly finished the effort and am now putting the resulting typefaces on myfonts.com. In this new effort I have both outline and solid versions of each pattern so that the user has much greater flexibility than with the first efforts. To aid the user in using the fonts, for each there is a gallery file in a pdf format that shows what characters are needed to get each tessellation pattern.
TessiePuzzlePieces contain puzzle pieces. The reason I created these shapes can be found at the link.
TessieStandingBirds was a result from a quest to see how many different Heesch types I could illustrate with birds standing on the backs of other birds.
TessieFlyingBirds has a large variety of flying birds. I tried to limit the use of characters that are not readily reached from the standard keyboard, so some flying bird shapes are on other Tessie fonts that are in the process of being put on Myfonts.com.
This illustration below shows three ways these fonts can be used. On the left is the solid style by itself, in the middle the solid style is overlaid with the outline style, and on the right the outline style is alone This shape is unusual because there are two ways to tile it. In the top six row of the picture, birds are flying both to the left and to the right. In the bottom four rows birds are flying only to the left.
For those who like the technical details of tessellations, the top birds are tiled as Heesch type TGGTCC while those on the bottom are tiled as Heesch type TG1G1TG2G2.
