Japan?s National Institute of Advanced Industrial Science and Technology (AIST) has developed a device that uses lasers to project real three-dimensional images in mid-air.
...

The newly developed device, however, creates ?real? 3D images by using laser light, which is focused through a lens at points in space above the device, to create plasma emissions from the nitrogen and oxygen in the air at the point of focus. Because plasma emission continues for a short period of time, the device is able to create 3D images by moving the point of focus.

At the demonstration, bursts of laser light were emitted 100 times per second to form shapes in the air up to 50 cm above the device. Heat from the laser caused the air to expand, producing a crackling sound that resembled a series of tiny explosions.

Makes UFO creation a snap. I think I smell a light saber cooking somewhere.

I forget what it's called but the other technology that creates an image in mid air is way cooler. Annandtech has an article on it somewhere.
