"The GNOME desktop environment and its underlying Gtk+ widget
toolkit—which provide a user interface and a standard set of
applications for Linux—have an elaborate theme system that
enables users to customize the appearance of their desktop.
"GNOME has attracted a vibrant community of open source artists
who are collaborating to produce aesthetically sophisticated visual
styles for the desktop environment. Many custom GNOME themes are
published in online galleries so that they can be downloaded and
installed by regular end users. The most popular of these
repositories is the GNOME-Look.org website, which has become the de
facto standard home of downloadable GNOME theming content.
"Although a wide variety of custom widget and window styles are
available, it can be challenging to find the ones that are truly
elegant amid the overwhelming volume of garish eyesores. In this
article we will look at a selection of some of the best themes for
the GNOME environment. Some of them are community-driven efforts
and some of them come from well-known Linux distributions."
