Robert J. Lang has been an avid student of origami for over thirty years and has over 400 designs catalogued and diagrammed. His work combines aspects of the Western school of mathematical origami design with the Eastern emphasis upon line and form to yield models that are at once distinctive, elegant, and challenging to fold.
Areas of his site include:

The 2007 Origami Design Challenge
Lang includes this description of the topic: "A plant. Not a leaf, or a single flower, but a full plant. (Roots, pot, ground are optional.) You pick the species: moss, fern, herbaceous, woody, big, small, weed, or tree; it's your choice. But whatever it is, it must be folded from an uncut square."
