Wow, a 3D Laser projection,
“It’s not exactly a hologram, but Japan’s National Institute of Advanced Industrial Science and Technology (AIST) has developed a 3D display that uses intersecting infrared lasers to create small amounts of plasma emission in mid air. By controlling the position of the focal point in the x-, y-, and z-axes, the visible plasma dots are capable of forming letters and simple shapes in 3D-space.”
