RegHarware: "In the spotlight at the Consumer Electronics Show this year was 3M's Mobile Projection Engine, a tiny projector - the vision is that we'll all have one embedded in our mobile phones etc.
Such products have yet to see the light of day, but the next best thing has: the 3M MPro110 portable projector.
About the size of a chocolate bar and 22mm thick, the 3M MPro110 features both composite-video and VGA inputs. It's the VGA addition that earns it the 'Pro' moniker. The picture comes from a tiny LCoS (liquid crystal on silicon) panel inside the machine."
