Here's my gallery of origami tessellations representing the 17 wallpaper groups.
Read here about wallpaper groups. Some applets for wallpaper designs: Escher Web Sketch, JWallpaper. Fanatastic kaleidescopes of each symmetry type.
Instructions for my origami trefoil knot. The basic technique comes from Thoki Yenn's Umulius Rectangulum model, so fold that one first!
