An anonymous reader noted a USC research project that is coming ever closer to bringing the classic Star Wars communication holograms from Tatooine to Earth. There's nifty video and some high resolution pictures of Tie Fighters projected into 3-D. Still no clear way to project it from an astro mech droid, but I'm sure that's coming.
