Better icons for the admin menu of WordPress 2.7: select an included icon set (Fugue, Silk, Tango, Tango 2) or add your own!
“To tangofy something”, usually an application, means to make new icons for it, or to add icons to it, that follow the guidelines of the Tango Desktop Project. The first versions of Tangofy —0.0.0 up to 0.0.6— were just that: One set of Tango-style icons to improve the admin menu of WordPress 2.7. Hence the name.
