Dubbed "The Battlefield" due to it's battleship-like shape, this amazing D.I.Y. three-hole, pinhole camera uses three simultaneous rolls of 35mm film! This will be an awesome summer project... Built from cardboard, tape, tin foil, felt pens, nails and bottle-tops (amongst other things you can find in your junk drawer). The three roles of 35mm of film run along the length of the box. Complex but comprehensive, you can find the instructions here, with handy diagrams, supply lists and videos. The photos it takes are super-cool!
