Graphical user interfaces (GUIs) are disclosed. One GUI includes a 3D object. The 3D object has a plurality of surfaces. The surfaces include one or more surfaces associated with a first user and one or more surfaces associated with a second user. The 3D object is rotatable in order to selectively display at least one of the surfaces. Rotation of the 3D object around a first axis changes the selectively displayed surface between the one or more surfaces associated with the first user and the one or more surfaces associated with the second user. Rotation of the 3D object around a second axis changes the selectively displayed surface between one of the one or more surfaces associated with the first user and another one of the one or more surfaces associated with the first user. The GUI may be implemented on the display screen of a medical device.
