USB CARTRIDGE turns 35mm film cameras into digital. “The RE-35 cartridge, in place of film, has a pull-out “sensor” that captures the images and saves them to flash memory within the cartridge. When plugged in to a computer, the cartridge charges and transfers images with built-in software.” I’m not sure if this is real, but I like the idea.

UPDATE: No, not real. I still like the idea, though.
