Custom map wallpaper. (Yeah, you read that right.) Wallpapered can print any postal code onto any size wallpaper for your home or office! All they need from you is a postcode or specified area and BOOM. Done. Your map wallpaper can even be customized in any color. So, what would you print – your favorite city, your hometown, your current town? I think I’d have to go with my home city of Pittsburgh, there’s nothing much better map-wise than the confluence of its three rivers.
