I have heard a lot about how holographic technology will progress in the near future, and have looked at how complex the equipment needed is. Will it be possible in the near future to have holographic projecters in the home, for example instead of TVs? How hard would it be to film and show a 3D show. At theme parks, there are 3D shows, but the machines needed are huge, and 3D glasses are needed. Are such items needed all the time?
