If the truth be told,  it has already been seen in many sci-fi movies.Audiences are very familiar with a scene that objects float in the space. The images were so real and flawless in those scenes, if you reached, you could almost touch them... No one could distinguish the difference between illusions and reality... At that time it was hard to believe that the objects we saw on those movies which float in mid air were actually three dimensional reflections of the original figure that were projected forward to create amazing and unbelievable scenes.

Beliving those that one day technology would enable us to create and project detailed three dimensional images of any real or animated object, make them fly in mid-air and see them without any special glasses were only a childhood dream and thinking that one day those we saw on movies could become true was turely beyond our imagination.

After years, the childhood dream has come true... and now we know; it is not a dream anymore...
