What useful applications do you foresee for standalone holograms (i.e. holographic technology that does not rely on glasses or a screen)?  For each use case you propose, please answer the following: 

1. What is the situation or experience in which you propose to use holograms? 
2. In this use case, what do the holograms depict?
3. What is the benefit of holograms in your use case?  Why does your use case rely on holographic technology and not traditional 3D technology?
4. Who is most likely to use holograms in this way?  To whom is this most relevant?  

Considerations

Please consider the following example use cases as you brainstorm new and creative ways to use holography:

1. A used car dealership shows a holographic display of a car at a tradeshow.  The hologram may be smaller in size than the real car but is otherwise indistinguishable in quality.  The hologram allows a crowd to see the car from any angle.  
2. Many people could gather to watch a hologram of their favorite artist perform, creating an experience with an entertainment value similar to that of a live show!
