By harnessing the power of tiny waves dancing in an electron sea, Japanese physicists have developed a novel way to project holograms that don’t change color when you move your head.
“In a conventional hologram, if you change the angle, the color changes,” said optical physicist Satoshi Kawata of Osaka University in Japan. “Our hologram shows natural color at any angle you observe.”
The researchers’ machine takes advantage of how beams of light trigger waves of activity in free electrons, unattached to any atom, arrayed on a metal surface.

I don't know about everyone else (I see someone above mentioned Project Bluebeam already) but this just makes me wonder what trillions of dollars of military funding across so many years has accomplished as far as holograms in the US.
It's sad that in other societies technology is seen as benefiting everyone, but to the US, technological research and development is inevitably of a military value first and foremost, and that's where the most money is poured into it. And then you never get to hear about what they've come up with, of course.
