Complex Anime Origami. Photos of 3d sculptures of anime characters, made of paper. Some are pretty risque (and furry). The level of detail makes it look like these are huge, almost life size, but this one is sitting on top of a DVD case. Some of these would freak me out a little if they weren't so amazing. (site is in japanese, and geocities. Even so, it's worth looking at)
You can download instructions on how to make some of them. He is selling some of the instructions (I think), others are free.
