A user interface includes a first menu comprising a first set of selectable options
circumferentially disposed on the first menu. In response to a selection of an
option from the first menu, a second menu is displayed. The second menu may be
concentrically-disposed relative to the first menu. The second menu includes a
second set of circumferentially-disposed, selectable options, which may or may
not be hierarchically related to the first set of selectable options.
