Close up of the texture on the gate of one of my carabiners. Shot using a pinhole.

Pentax K-x - 30 sec - f/0 - ISO 6400 - ~pinhole

Dim artificial lighting.

Used GIMP to adjust levels, scale and watermark.

One of the features of pinhole photography is that the very small aperture makes the depth of field (distance between closest focus and furthest focus) huge. So huge, in fact, that objects on your sensor (like dust) are in focus. I'm not quite certain if this allows you to focus on objects really close to your camera as well, or if there's a different effect causing it, but it does seem to work well with really close focus shots (such as an object that is really small). The lighting wasn't great to start with, but the small aperture also required a long exposure with very high ISO, causing a lot of noise. Also, the pinhole wasn't very good, so its a bit blurry too.
