A system of displaying hierarchical information in a user interface includes displaying a first plurality of icons aligned in a first arc course on a display device (block 102), selecting one of the first plurality of icons using a user input device (block 104), rotating the first plurality of icons to position the selected one of the first plurality of icons to a front position (block 106) of the first arc course in response to the selecting to define a first selection indicator and displaying a second plurality of icons aligned along a second-level arc course (block 112), the second-level arc course displayed adjacent to and positioned co-axial with the first arc course (block 124), and the second plurality of icons representing sub- hierarchical data for the first selection indicator (block 110).
