Description:

Kali lets you draw symmetrical patterns based on any of the 17 tiling groups. Kali does not assume the user knows how to read, so even the youngest children can enjoy it.

Older students can systematically explore the wallpaper, frieze and rosette groups. The command "Show Singularities" and the Conway and IUC notation provide support for a theoretical analysis.

Freely available for both Windows and Macintosh computers.
