This is amazingly cool. The Virtual Window Project: "Flat panel technology is quickly becoming bigger, better, and more affordable, which will allow for all sorts of fun ways to transport your domicile to wherever tickles your fancy. This is my modest attempt to view something more interesting than my neighbors."
Home Depot should sell a window like this already manufactured. Then, you could join a web service and download new animated locales for a microfee. Or even better, live feeds of really cool places.
Commercialization aside for now, this would be a great feature project for Make and it's just really cool. Look at this: San Francisco Wharf. (via Waxy Links)
