What happens when you take a perfectly good invention — one that’s been around for several hundred years — and completely rethink it? That’s what an enterprising musician and composer named Stephen Scott has done with the grand piano.

The journal Nature reports the breakthrough by US
researchers who developed a novel material in which holographs can be
created in minutes. The images that the material can capture are almost as sharp as those broadcast on US television. 
The polymer can also be made into large screens opening up many more possible uses for the 3D images.

The Washington Post has an article about the Intelligence Advanced Research Projects Activity’s
