Shape Extension
In the X Window System, the X Nonrectangular Window Shape Extension allows windows to be given arbitrary, non-rectangular shapes.
Two well-known applets that use the shape extension are oclock, which is a simple round analog clock, and xeyes, which shows two googly eyes that follow the cursor on the screen as if they were watching it. Most X Window systems have one or the other (or both) in their standard installations. In addition, some window managers use the shape extension to draw non-rectangular icons.

Famous quotes containing the words shape and/or extension:
“This whole day have I followed in the rocks,
And you have changed and flowed from shape to shape,
First as a raven on whose ancient wings
Scarcely a feather lingered, then you seemed
A weasel moving on from stone to stone....”
—William Butler Yeats (1865–1939)
“Slavery is founded in the selfishness of man’s nature—opposition to it, is [in?] his love of justice.... Repeal the Missouri compromise—repeal all compromises—repeal the declaration of independence—repeal all past history, you still can not repeal human nature. It still will be the abundance of man’s heart, that slavery extension is wrong; and out of the abundance of his heart, his mouth will continue to speak.”
—Abraham Lincoln (1809–1865)
