A multifunction device having a touch-sensitive surface displays graphical objects that represent digital content products, each graphic object having a front side image and a back side image. An initial display shows front side images of objects representing digital content products. A user input selects a graphical object, resulting in an animation that simultaneously flips the graphical object over and enlarges it. At the end of the animation, the back side is displayed, and is larger than the initial front side image. A second user input on a front side image of a second graphical object results in a second animation that simultaneously flips the first graphical object over and reduces its size, and also flips the second graphical object over and enlarges it. The front side image of the first graphical object and the back side image of the second graphical object are thereby concurrently displayed.
