Just because Leia was talking through R2D2 to Luke doesn't really mean it is possible in reality.

Just throwing light into a room and hope it forms a 3D image, like a moving person or an attacking shark, isn't exactly holography.

We have holograms right now. Not as sophisticated as this one. But unlike hover cars we are on the right track.
