Tiny Projectors

Tiny projectors - like this one from Microvision - are big this year, although picture size and quality isn't necessarily so. I overheard one presenter say you could project an image up to 200 inches with one of these types of projectors. Technically, I suppose you could send a photon from one of these projectors to Mars, but that doesn't mean it's watchable at that size or distance.
