The iPhone SnapShop app allows users to download furniture images from the ShapShop database and visualize how they will look in their house or office. The use of 'augmented reality' allows the furniture selected to actually look as if it's in the room so that the user can determine whether to purchase it or not.
Use the iPhone SnapShop app to share new interior designs with friends or colleagues via email, Facebook or by saving them to Evernote.
Implications - This is one of the most incredible uses of modern technology that I've ever seen. The iPhone snapshot allows you to do something that we could only fantasize about as children -- what's not to love?
