The world techies (Germans) has done this nice job. Everything is becoming so small now a days, starting from Computers to Camera. This projector is from Fraunhofer Institute for Applied Optics & Precision Engineering in Jena. Its a 16mm wide projector which works by shooting LASER on a mirror. These projectors can be embedded into a Portable Medium, but they didn't convey anything about the price & availability. [SOURCE]
