Mr. L’s Math

The good people at the online Geometry Center have brought us a wonderful java app that creates any of the 17 different wallpaper groups, as well as frieze and rosette patterns. The java app allows you to pick your favorite color, choose from one of the many patterns, and create your own unique design. You can select a different color at any time to get a multi-colored creation. If you have a screen capture utility such as SnagIt or Snippy, you can then copy/paste your artwork into a Word or PowerPoint document, or post it on your website.

This website typifies the best blend of modern technology and art to create a medium for creativity within a mathematics framework. You and your students may wish to explore why there are exactly 17 different wallpaper groups; it’s a fascinating story.

Kali: Symmetry Groups may prove to be a motivating website for some of your students who need an “extra boost” to get interested in art or geometry. Enjoy your visit on the website!
