Winscape is a remarkable new kind of "window" consisting of two 46" 1080p plasma monitors hung vertically and mounted into the wall. But the best part of the display is that it uses a Wiimote to determine where the user is standing - and then alter the display accordingly.
Take a look at Ryan Hoagland's do-it-yourself virtual window video. And remember that the parts cost just $3,000!

This display should remind sf readers of the ersatz windows used in Philip K. Dick's 1969 novel Galactic Pot-Healer:
"Home" consisted of a room on a subsurface level of a huge apartment building. Once, the Jiffi-View Company of greater Cleveland came by every six months and created a 3D projection, animated, of a view of Carmel, California. This "view" filled his room's "window," or ersatz window.

The Winscape device, as advanced as it is, still lacks one component to come up to Dick's vision; it needs a psycho-lease encephalic gadget to make you believe it's real.
