Pinhole photography, Part III

For those of you who have been living under a rock and don't know what StumbleUpon is, it's a tool to help you discover websites you might like, based on the interests you specify and which websites you give thumbs up or thumbs down. It's something I turn to when I'm bored because I know I'm bound to come across something interesting. Stumbling across this website is what got me thinking about pinhole photography recently.

Photographer Justin Quinnell took a series of pinhole photos, including the one below.

What is so cool about this photo is that it was taken over a period of six months! Not multiple exposures, but one single shot!
