Pinhole Camera

by Thingiverse
This is a plan for a pinhole camera that is made from layers of plywood (or anything layerable, really ;). It has a round image plane, the idea is to get a broad field of view.
It's not yet tested, so I don't have any idea what kind of pictures will come out of it, but I'm building two right now.
update: Attached a picture made with the cam. It works. :)
