Sense of humor has nothing to do with it-I just don't think false 'information' has any place in a rational discussion, whether intended as humor or not.

Just like all real holograms are-- a static image permanently stored on a holographic film or a solid substrate. Not projected into the air. What the CNN article was about is that someone has developed a medium for storing holograms that can be erased and rewritten. But no matter if they did get the erase time and the rewrite time so fast that it can produce full-motion video, it will still be just an image embedded in the surface of the material like that little bird on your credit card. It will not float above a surface like Princess Leia. That is fantasy, not reality.

I see that kits are still available, and cheaper than when I first looked at them maybe 10 years ago:

I guess we're in the realm of competing experts then.
http://en.wikipedia.org/wiki/Holography talks about the 3-D holograms, which are the *original* holograms. I'm not a lexicographer so maybe Gresham's law applies here, but I tend to keep the original meanings for words. And by that meaning, the pictures on credit cards, etc. are hot holograms.
But I do see that your references call them holograms, so I guess at this point I'll just note that there appear to be two different meanings for the word.
As to how much science I know, I at least know enough to tell that something which has been demonstrated in the laboratory, regardless of the name that's applied to it, is not fantasy.
