Three more tessellating typefaces have been added to Myfonts.com. Included is a fourth typeface of birds, TessieXtraBirds. When playing with TesselManiac and before it TesselMania, I have had the tendency to see bird possibilities much more readily than other shapes.
TessieMoreStuff. The plane shape has four edges that are all shaped with identical center-point rotation. The poster has them in three different tiling arrangements.
The musical notes from TessieMiscellaneous are a based on a triangle. It is a pattern unlike any that I have seen elsewhere.
