3D Animations in Mid-Air Using Plasma Balls

3d-plasma-displays.jpgJapanese boffins are now making animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules: up to 1,000 brilliant dots per second, which makes smooth motion possible. They could be used as street signs, advertising or to create giant plasma monsters to destroy entire cities. Maybe.fig5.jpg
