I wake up this morning to see that google had placed an ad for buying a holographic 3D projector. That's really interesting. So I guess google scans the blogs and place adds that are appropriate to the post. Maybe it will help me.

reuniting with relatives and friends through holograms

I know this is creepy but I think it's very possible. Kind of like a dream! When a friend or relative comes to you in a dream. It's so real.   This could one day be very possible with holographic images.  Maybe there is no such thing as being lonely ever again with holographic family and friends!  Maybe even holographic pets.
The world may come this one day.   There could be more opportunity in a virtual reality. And who's to say what is more real.  Tupac did a song as a hologram at a concert a couple of years ago. People completety
freaked out. Is this the future? First bring back dead rock stars and do world wide tours.  Guaranteed people will buy tickets
