Pretty pretty sky

Japanese researchers have developed a laser display which can produce "real" 3D images in the air, instead of the pseudo-3D images on two-dimensional planes created by current devices, according to an article in New Scientist (via Roland Piquepaille in his Emerging Technology Trends blog). While these displays are still in demonstration stage, they could soon be used to shine giant 3D ads in the air.

The system has been built by the National Institute of Advanced Industrial Science and Technology (AIST) and Keio University, in collaboration with Burton Inc.
