Tess is a symmetric illustration program that supports eleven rosette, all seven frieze and all seventeen wallpaper symmetry groups. Tess also supports all 28 types of Heesch tilings. Illustrations can be printed from Tess or exported to JIF, PCX, DXF or SVG formats. With Tess, you can quickly create symmetric planar illustrations. While you draw, Tess will automatically maintain the symmetry group you have chosen.
