All shapes in this software have the same side length.
The shapes differ in their number of edges and in their angles.

Shapes can be grouped, copied and pasted.

This application is also useful to learn or to teach about geometry.

Powerful app

Interesting app with a ton of options. As a professional tile artist working with Islamic geometric pattern, this app is quite delightful. The amount of power it has, and the huge range of possibilities is staggering. This app makes it possible for people who have no background in Islamic pattern to create beautiful designs in minutes. Outputs in multiple formats if you want to use it with a printer or digital cutter. For $10, it is a steal! Anybody playing with pattern should be fascinated and intriqued by this app.
