Displaying a three dimensional user interface

In a method for displaying a three dimensional interface on a device, a scene is displayed on a display of the device and a three dimensional user interface control with three dimensional effects is displayed on the display of the device, the three dimensional effects based on a virtual light source, a virtual camera, and a virtual depth of a three dimensional object relative to the scene. A change in the position of the device relative to the virtual light source and the virtual camera is detected. The three dimensional effects are dynamically changed based on the change in position of the device relative to the virtual light source and the virtual camera. Orientation of the virtual camera is dynamically changed to change the display of the scene and the display of the three dimensional user interface control to a new perspective based on the change in position of the device relative to the virtual light source and the virtual camera.
