Hmmm, must be a new zeitgeist. A student who joined my alt-p class this
summer went about turning his D100 into a pinhole camera. He converted a
Nikon body cap with a 1/2 inch hole in the center covered with a brass
shim stock. Pinhole was drilled by hand with .00135 diameter drill and
slightly polished. The image at this range covers the sensor, allowing
for a "non-round image.
I've put up a couple of these. The keyboard was shot with a flash, with
the camera set to manual and tested (that's what's great about the
digital pinhole...instant preview).

Unfortunately, it was still kinda big and the focal length kinda long compared to what I wanted. Remember that the CCD is quite tiny compared to 35mm film. So the resulting lens is about equivalent to an 88mm lens on a 35mm camera, at about f/67.
