The prototype is now on show in Tokyo, and as you'll see in the video, the 96 by 128-pixel resolution looks better than you might expect. In person, objects appear to have depth, and can be viewed from all angles.
The cylindrical display is about 10.6-inches tall (and 5.1-inches in diameter). Sony doesn't seem quite sure what to do with it at the moment, but says it's considering various uses, like digital signage, or even a digital photo frame for the home. [Sony via Network World]
