The article's a bit too big for a quote so here's the bit I found most interesting.
The demonstration was put on by Forth Dimension Displays, a component maker that has managed to squeeze a functional, commercially viable 1080p monitor into a display area that measures a little less than an inch across diagonally (the company has also recently prototyped a similarly sized screen at QXGA resolutions of 2048x1536—the same pixel count as the new iPad squeezed onto a fraction of the size). By putting one of these HD displays a few inches in front of each eye, you can create an all-encompassing 3D effect that covers a roughly 100 degree field of vision in front of you (Forth Dimension also makes wider displays that can extend that vision field even further).
