These are not real windows.
If you have a room that needs a view, mount some plasma displays on the wall with your own gorgeous video.
"Real windows are interactive – unlike a painting on the wall. When you move your head in relation to a window, the view outside shifts up/down/left/right. If you want to see something in the window’s right periphery, you can move your head left to bring it into view.
We can simulate that effect if we know the location of the viewer’s head in relation to the Winscape displays. The effect will only look correct to the one person in the room wearing the tracking device, so it’s presented more as a fun party gimmick than as a feature for full-time use."
