"By creating plasma in open air with lasers, Japanese scientists are working on a true 3D display.

The Japanese National Institute of Advanced Industrial Science and Technology (AIST) announced an exciting breakthrough in optoelectronics -- a working three dimensional display. The display does not rely on any sort of optical illusion or disorientation. Instead, infrared lasers are aligned to converge and create small amounts of plasma. The plasma acts as a floating "dot" on top of the laser grid. "
