Abstract

Methods, systems, devices, are described for displaying a document. In one view, a first substantially rectangular shape containing a current page of the document may be displayed adjacent to a second substantially rectangular shape containing a number of pages other than the current page. A rotational motion input may be received at the device, and the first and second shapes may be updated based on a new current page identified by the rotational motion input. In another view, a number of curved shapes may be displayed in a nested arrangement defined by a spiral, each of the curved shapes being associated with a portion of the document. A current page may be stored, and a rotational motion input may be received. The current page may be updated according to at least an end point of the received rotational motion input.
