Explore the beauty of mathematics with ’Simitri’, an iPad app which lets you create beautiful colourful patterns based on simple mathematical rules. This app introduces transformations and symmetry groups (’ wallpaper groups’) and then allows you to draw your own patterns using your chosen symmetries. It is an interesting fact that there are precisely seventeen symmetry groups in two dimensions, and this app explains each one with interactive animations and examples from art and archaeology.

When you’re happy with your artwork you can save the images to your iPad, your camera roll, or show them off on Facebook and Twitter. A public gallery also showcases the best designs from around the world!

  • Learn about the 17 wallpaper groups
  • Understand translations, rotations, reflections and glide reflections with colourful animations
  • See examples of the beauty of symmetry and mathematics in the decorative arts and historical artifacts
  • Draw your own patterns using a choice of templates and colours
  • Save your designs, or post your designs to Facebook or Twitter
  • Submit your designs to the public gallery for everyone else to see!
