Tiny projector from Microvision is shown at the CES 2008:

Dubbed SHOW, the lensless PicoP projector is designed for home and business use, and uses tiny lasers to shoot a WVGA (848 by 480, roughly DVD resolution) image on virtually any surface that isn’t a dark color or textured. It can even project onto curved and uneven surfaces. From a distance of two feet, it could project a two-foot diagonal, full-color image on a white T-shirt. From five feet away, it could show a five-foot image on, say, a white wall or ceiling.
