I just wanted to start a discussion on the amazing holograms that were used by CNN. How were they done? How much do they cost? How will they be used in the future?
This is quite a skeptical [article](http://news.cnet.com/8301-11386_3-10082802-76.html)about the whole thing. While the points raised are valid to some extent I think it's a very exciting technology with all sorts of potential. I expect it will be deployed on the high end speech/lecture circuit soon. It could be used to create some really innovative museum exhibits. I wonder if the Obama campaign will figure a way to make use of it in 2012.
