Pedagoguery Software Inc. has released an update for Tess, bringing it to version 1.06. Tess is a educational mathematical app designed for symmetric planar illustrations. The update has several improved tiling features including a Heesch tiling function. According to Pedagoguery Software:

Tess 1.40 for the Macintosh is now available (December 13, 2001) for download.

The previous version was Tess 1.06, released November 9, 2001.

Changes since the previous version:

You can now create a Heesch tiling by selecting "New Heesch Tiling" under "File". Information on Heesch tilings can be viewed by selecting "Heesch Tilings" from the help menu

All 28 Heesch tilings are supported; Heesch tilings are symmetric illustrations that use a single type of tile to fill the plane without gaps

Translational symmetry vectors for the current symmetry group can now be shown or hidden using the "Show Translations" menu item in the "View" menu

You can now adjust the translational symmetries used for wallpaper groups. First show the translational symmetry vectors and then move the non-vertical vector's head or stalk to adjust its length or orientation; single-clicking will allow you to enter a numerical value

You can find more information about the Tess update at the Pedagoguery Software Inc. Web site. Tess 1.06 is available for US$36.00.
