The Coolpix S1000pj's built-in projector is an innovative first for digital cameras, but first combo honors go to the Wittnauer Cine-Twin 8mm film camera: special base and reel add-ons let it convert into a projector back way back in 1957.

Wittnauer was actually a famous jeweler of all things, and the expensive Cine-Twin was only sold in jewelry stores. Ultimately, the novelty wasn't enough to overcome practical concerns like price, huge D-cell batteries, and a delicate and expensive glass bulb.


Interesting extra: Even before the Cine-Twin, the Cinématographe film camera/projector/developer was invented by French inventor, Léon Bouly, back in 1892. It wasn't like you could just go and pick one up, though.

The more things change, the more they stay the same, right? [Retro Thing via OhGizmo!]
