The prototype is now on show in Tokyo, and as you'll see in the video, the 96x128-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]
