Hands-on with Arqball Spin, the app that lets you create interactive 3D models

Sometimes, two dimensional photos, even those taken by a 41-megapixel sensor, simply aren't enough to accurately depict a three dimensional object. Enter Arqball Spin, a free app that lets anyone with an iOS device create high-quality 3D models of whatever they like. Using the iPhone's camera, the app takes a series of images and uses some software black magic to create the finished product. The model, or "spin", can be cropped and adjusted (brightness, saturation and contrast) like a regular photograph, plus users can create custom annotations to identify or comment on specific parts of the "spin" as well.
