A graphical user interface is provided for navigating and/or manipulating content simply via touch of a touch-sensitive surface. The content may include discrete content items (e.g., songs, video clips, documents, web pages) and/or actions (e.g., place a call, read a message, play a game), and may or may not be hierarchical in nature. The interface may be presented on a touch-screen display, such that a user may navigate to a content item or action via a single touch on the display (e.g., with a finger or other tool), followed by gliding through any number of levels or clusters of nodes (representing content items, content compilations/categories and/or actions). The desired content item or action may be initiated automatically (e.g., opened, performed) simply by touching it, by lifting the gliding finger or by performing some other input (e.g., tapping a node, speaking a command, touching with a second finger).
