A system for navigating content may be responsive to movement of a hand by a user toward and away from a display surface. The content may be visually arranged and presented as a stack of visual panes. Moving the hand away from the display surface causes the panes to move upwardly through the stack. Moving the hand toward the display surface causes the panes to move downwardly through the stack. When moving upward, the otherwise topmost pane is deactivated and hidden. Upon reaching the top of the stack, a pane is activated and displayed in full.
