Graphical Shells
A graphical user interface (GUI) represents programs and data using visual symbols instead of text. Graphical user interfaces became feasible as the cost of interactive computer graphic hardware declined. Most graphical user interfaces develop the metaphor of an "electronic desktop", where data files are represented as if paper documents on a desk, and application programs similarly have graphical representations instead of being invoked by command names.

Famous quotes containing the word shells:
“The only fruit which even much living yields seems to be often only some trivial success,—the ability to do some slight thing better. We make conquest only of husks and shells for the most part,—at least apparently,—but sometimes these are cinnamon and spices, you know.”
—Henry David Thoreau (1817–1862)
