This camera... is a great camera. Note that it does not actually function... though with a thick enough cardstock and a few simple modifications to the design, it could probably become a pretty awesome pinhole camera. The lens on this is actually a movable part of this model, which can be extended and contracted.

The idea for this model was actually given to me by my boss at my day job at the time. Hell, he even payed me to work on it because there wasn't a whole lot else going on at the office that day. Thanks, Brahim!
