Using a box designer program, I created a pinhole camera with a removable film back holder.

Behold! Pinholio V.1.1!

Currently still in the prototype arena, but I'm constantly modifying ideas to make it dead simple to use. Next will be a film magazine a-la large format cameras, as well as a primitive shutter and tripod socket. Currently uses one frame of 35mm or a 1.5 inch square of print paper.

Any ideas are appreciated.
