BoingBoing has a link an artist's site with pictures made from a unique pinhole camera. The pinhole camera is actually made from photo-paper, so it is one-use.

To simplify these cameras as much as possible I made them out of the 11x14 inch photo-paper itself. There is no film in the camera because the camera is the film. Like a salad bowl made of lettuce leaf, and consumed with the meal, the camera doesn't exist after its utility is fulfilled. There is no machine. It is more of an arrangement than a thing.

Since it is color paper, sensitive to the full spectrum of visible light, there is no "safe" light recommended for darkroom work. Each paper box camera is cut, folded, and constructed in the dark and kept in a dark bag until its moment in the sun has come.

So. Cool.
