Abstract: A graphic user interface, such as a standard functioning mouse or track ball, which has the shape and/or appearance of various different characters, such as animals and which may be sized for use by children. The graphic user interface also has various removable and interchangable parts so that its appearance can be changed without interfering with functioning of the device. The graphic user interface can have added features such as sound an/or light generating features so that normal operation of the buttons causes the production of a sound or sounds which depends on the shape applied to the graphic user interface. Depressing the buttons can also cause bulbs or LCDs positioned on the graphic user interface body, particularly in the eyes of the character, to light.
