Pinhole Self Portrait

The self-portrait below was created by punching a small hole in the body cap of my small Rebel XTi and using it as a pinhole camera.  I used a small maglight to light myself during the exposure (20 seconds) and then processed the image in Lightroom.  The coverage using the 'cap pinhole' doesn't even fully cover the 1.6x crop sensor, so I wouldn't even bother trying it on my 5DII, but I think it could produce a lot of interesting images on any 1.6x camera (Canon xxD series, Rebel series, 7D) and would be even sized on 1.5x cameras (Nikon DX).
