I love holograms! My first interaction with them was at the Luxor in Las Vegas a million years ago. I was hooked. They are fascinating!
Then I recently saw this... which actually kind of freaks me out - okay?
But, there is also this... which is very cool and has excellent (useful) applications.
I dunno - but, I think this stuff is amazing, even if, in the case of the pop star - a little creepy.
What do you think?
