Claim:
A method of operating a multi-touch graphical user interface on a computing device, comprising: displaying a group of objects on the graphical user interface in a group representation, wherein the group of objects comprises three or more objects and wherein the group representation comprises a stacked organizational representation of the three or more objects that exposes a first portion of the three or more objects and occupies a first portion of a display; receiving a first multi-touch input in which a first number of touches associated with the group representation are moved on the graphical user interface, the first multi-touch input comprising touches of a first, equal number of fingers of each hand of a plurality of hands at a border displayed around the group representation and wherein each hand is moved a distance relative to each other hand; in response to the first multi-touch input, changing a scale of the objects in the group representation so as to change the portion of the display that the group representation occupies from the first portion to a second portion of the display; receiving a second multi-touch input in which a second number of touches associated with the group representation are moved on the graphical user interface, the second multi-touch input comprising touches of a second, equal number of fingers of each hand of the plurality of hands at the border displayed around the group representation, the second number being different than the first number and each hand being moved a distance relative to each other hand; and in response to the second multi-touch input, changing the group representation to a different group representation that comprises a tiled organizational representation of the three or more objects that exposes a second portion of each object of the three or more objects that is greater than the first portion of each obiect of the three or more objects and occupies a different, greater portion of the display than the second portion of the display.
