Twelve South has been building a collection of matched dual-screen desktop (wallpaper) images. Recently, the third in the series was released. The company says: "At Twelve South, we have a passion for amazing images, beautiful visuals, and great design. We love seeing our collections – Fall in San Francisco and Scotland Vacation – on dual-screens around the world. For our third collection, we partnered with the amazing photographer, Scott Gordon, to capture the San Francisco Bay during the golden hours - that time before sunrise and sunset when the light is perfect for shooting. The resulting images are magical – we're thrilled to share them with you." The webpage has links to the three the collections and how to install them. Of course, these beautiful images can be used on single display if desired.
