"Widgetbox is a directory and syndication platform for web widgets for blogs and other web pages. Our widgets work with TypePad, WordPress, Blogger, MySpace as well as most other blogs, sidebars or websites. No plug-ins are needed, and they're free!

A web widget is a small piece of interactive content (like an ad or a game) that can be dynamically embedded into a web page. Widgets allow for a new level of expression and creativity as personal web publishers use them to create value and interest in their blogs, social networks, personal home pages, and web sites."
