Visual expression of a state of an application window

A method for changing a visual state of an application window representation is described. The method includes steps of displaying an application window representation with a default visual state, and changing the default visual state of the application window representation to one of at least two different visual states. The entirety of the application window representation or a portion of the application window representation may have a change to its visual state. The visual states may be a change in color, pattern, and/or texture. A group of visual states changes may correlate to an animation. Visual states may be defined by a default or user configurable. Visual states may change over time or in response to an event. Visual states may change back to a default state when the application window representation is accessed.
