If you enjoyed your Google widgets (calendar ; clock etc) on your Google personalized home page and desktop you can now add them to any website.
Google has put together a Gadget Directory, where you can pick your favorite widget and copy the code to your website.
Most of the gadgets are not developed by Google. They are created by outside companies and web developers. Google makes no promises about performance, quality, or content and its not charging for inclusion in the gadget directory.
