Wanted to share an old screen capture of the Yahoo! Widget TV to give folks an overall idea of how the new Yahoo! Widgets look and work.
You will notice that at the bottom of the screen is a dock that displays widget snippets (dynamic icons). Once clicked, a widget opens up in a sidebar. Widgets can also enter a fullscreen graphical or video mode. The Connected TV environment comes with a Gallery Widget that is used to browse and add 3rd party widgets. Individual widgets feature a horizontal tabbed menu metaphor (very similar approach to the Widgetmatic 600 series). Each widget has a title area, a "Navigation Start Point" (usually where the content goes), a set of horizontal tabs (menus), as well as a global toolbar (at the bottom).
