A research firm in Japan has "developed a device that uses lasers to project real three-dimensional images in mid-air." Sounds cool, but that’s not all. It does this by exploding the air forming a brilliant white plasma. Oh yeah, now it’s mega cool!

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.
