Oh, and the whole thing is controlled with an iPhone app -- there are a few different views, as you can see in the video above. You can buy the Winscape software for $10 over on the website, and the remote app is $2 in the store, but of course you've got to buy the plasma televisions and Mac Pro yourself (and cut a window into your wall and/or install them all the way you want them). So no, it's not a very practical solution -- at least until houses come standard with video windows.
But it would be great to wake up every morning and be able to look out the window and see whatever you want to see. Maybe someday we'll see a setup like this as a more accessible investment.
