At the MAKE: Blog, Phillip Torrone points to a HOWTO and history of the Dirkon paper camera. Phil says:
Here's a fascinating project and history of the Dirkon paper camera. The name Dirkon is a play on words based on the combination of the parts of two words: Dirk- is the beginning of the Czech word dirka – pinhole, and -kon is the end of the name of a well-known Japanese camera. The site has a gallery, instructions, tips and printable templates to make your own.
