Karol Łuszcz is studying electronics at  Poland’s Gdańsk University of Technology. I’d say he’s on-track for an impressive career. This vector-graphics laser projector, his third prototype, includes three laser modules at 650, 532, and 405 nm wavelengths (making it more of an RGV projector, really).  Many parts were salvaged, for instance, from a DVD burner, a printer, and a “disco ball.”

Kinematic mounts for optical elements, and electronics to drive the mechanical scanners, were custom-fabricated. Components are mounted on a 3mm aluminum plate mounted in an aluminum briefcase modified with a projection aperture on the side. Magnificent, inspiring build. [via Hack a Day]
