I just learned a fun fact: the lightsaber props in Star Wars were made from the flash guns for Crown Graphic cameras like mine. To make it look more high-tech, they slid the LED display from a pocket calculator into the mounting bracket on the flash gun. Apparently large format photography enthusiasts are bitter because the flash guns have become rare and expensive these days, since all the nerds have cut them all up to make replica lightsabers. Hee.
