A digital picture frame has a frame bounding a touch screen that presents a user interface having first and second arcs of selector elements. The first are of selector elements is manipulable to establish an input genre root, and the second arc is manipulable to select an input branching from a genre root selected using an element in the first group. The arcs are rotatable to reveal previously unpresented selector elements when a person moves a hand along the respective arc.
