Created for the Japanese police department, the DORYU 2-16 pistol camera was designed to work as a fully functioning 16millimeter camera.

Unveiled way back in 1952, the cam-gun was originally designed to provide Japanese Police with a tool to catch criminals in the act, as well as photograph protestors. Equipped with a built-in flash system (for night shots) and a clip of five magnesium cartridges in the handle (as opposed to actual bullets), the DORYU 2-16 pistol camera was ultimately a failure with the general public, but remains as a testament to the early days of Japanese cool design.
