Deviant Art user minidelirium has created some of the most intricate papercraft art I've ever seen. She has created crafts of all sizes from a mini Kupo to a huge Zelda model. You should definitely check out her profile and look at the progress photos and more detailed shots of the characters.
Taken by themselves, the steel wire sculptures of Larry Kagan appear to be abstract creations. Under carefully positioned light, however, a more recognizable image appears. Kagan's shadow art plays upon the contrast between objects and their shadows, between order and disorder, and between the material and immaterial.
