Cambridge University researchers have created a more efficient holographic laser projector, capable of generating 200 holographs a second (which would make for very smooth video), which could see potential use in handheld devices, notebooks or PDAs. The image could be focused at any range and operates by "steering" light, instead of blocking and wasting light energy the same way current projector lamps do. Save your Star Wars references, though, as this is 2D video only, friend.
