Yahoo! Widgets are small, specific applications that you can run on your or Mac OS desktop. A Widget can do almost anything from displaying a weather forecast to playing a game. Widgets generally sit on your desktop and don't look like applications as we're used to seeing them in a standard window. Instead, Widgets tend to look like small pictures or animations. Yahoo! Widgets help you save time and stay current by bringing an always-updated, at-a-glance view of your favorite Internet services right to your desktop. The Yahoo! Widget Gallery offers over 4,000 desktop Widgets - the most available anywhere online. Yahoo! Widgets is the only major desktop Widgets platform that works on both and Mac OSes.
