Imagine: You wake up and look out the window and see a glorious sunrise over the ocean. That night, you watch the sun set over the Rockies... and you've never left your house. Winscape from Rationalcraft allows you to do just that.
By using a Wii interface and some clever software, you can now see anything you want outside your "window" with Winscape. Want to have the view from the space shuttle? No problem--Winscape can provide it all.
Winscape currently requires the person doing the viewing to have a sensor hanging around his or her neck, so it only works for one person at a time.
