This is just geekarific. The guy has built a series of origami monsters, mostly based on critters from the AD&D Monster Manual. Joseph Wu is my new hero.
My favoritest ever D&D monster, the Beholder, is pictured at left, and many others (including a mind flayer and two or three dragons) can be found in Joseph Wu's Origami Gallery .
Thanks to boingboing.net for bringing this to my attention!
