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:
“It was the most wild and desolate region we had camped in, where, if anywhere, one might expect to meet with befitting inhabitants, but I heard only the squeak of a nighthawk flitting over. The moon in her first quarter, in the fore part of the night, setting over the bare rocky hills garnished with tall, charred, and hollow stumps or shells of trees, served to reveal the desolation.”
—Henry David Thoreau (1817–1862)
