Could the idea of Star Wars style 3D holographic messages beamed out from R2D2 turn into a reality. Well, this new True 3D technology from Japan seems to suggest that it can. Based on a technology developed by AIST and Keio University back in 2006, this new projection system can be used to show pictures without the use of a screen. The system works by focusing laser light to produce plasma excitation from the oxygen and nitrogen in the air, which allows it to display images mid-air.
Ubergizmo, True 3D display doesn't need a screen to display images
