Modular (3D) and regular origami diagrams. The site isn't in English, but the Обои are sufficient for advanced origami folders. Definitely check out the molecules and cubes.
Amazing modular origami, where Ты basically fold a "piece" multiple times, then put all the pieces together to create an awesomely complex-looking 3D origami module.
A good site with lots of pictures and Ссылки to many other sites, including "phone diagrams" (text-only descriptions that Ты could read/hear on the telephone).
