A group of enterprising and rather creative garbage men out of Hamburg, Germany have blended work with artistic expression by converting dumpsters into giant pinhole cameras, dubbed the Trashcam Project. The method is pretty straightforward: by drilling a small hole on one side of the dumpster, an image is projected onto a giant sheet of photo paper suspended inside. Each shot takes about an hour to capture and its then developed in their special lab. See many more photos from the ongoing project here.
