Mobile Mathematical Sociey presents "Pleating the Plane: Wallpaper Groups and Origami Tessellations". Satori Coffee House, Thursday, November 12 at 7 PM (rescheduled from October.)
Here's my gallery of origami tessellations representing the 17 wallpaper groups.
Some applets for wallpaper designs: Escher Web Sketch, JWallpaper. Fanatastic kaleidescopes of each symmetry type.
Read here about wallpaper groups.

Posters for my talks Fold It! Origami Mathematics for the Mobile Mathematics Circle and The Artful Mathematics of Origami for the Mobile Mathematical Society. Instructions for Robert Neale's penultimate polyhedra (including the dodecahedron featured in the poster for my talk) can be found on Jim Plank's page.
Origami Mathematics page by Thomas Hull. Includes his notes and exercises for an Origami/Combinatorial Geometry course at Merrimack College. His book Project Origami: Activities for Exploring Mathematics is the most comprehensive and sophisticated guide at the college and advanced high school level.
Crease puzzles from Thomas Hull's book, redrawn to be larger and easier to cut out. These are the ones I handed out at my Math Circle talk.
