Forget hi-def TV. That technology is as old as the internet. The next generation of digital entertainment could bring entertainers into your living room as full-sized 3D holograms, bring cell phone voicemails to life with tiny images of callers or bring you face-to-face with Super Mario himself.

It’s an exciting time for physicists and other researchers who have spent decades trying to expand the applications of holography, the creation and manipulation of 3D images made by bouncing laser light around.

Last month, a team of researchers at the University of Arizona unveiled a critical breakthrough toward the elusive goal of holographic video, developing a technology that allows holograms to be rewritable for the first time. This allows 3D images to be changed many times per second, just like the frames in a movie.
