What we saw in the movies is getting closer to reality, in particular, speak to you from the movie Star Wars robot R2D2 when projected image with the cryptic message from Princess Leia like a three-dimensional hologram in front of Luke Skywalker it was just science fiction. But now developed IO2Technology number, the Heliodisplay M2 is capable of projecting images on a layer of smoke or steam in the middle.
