If you'd like to see widgets not only on the dashboard but also on the desktop, do this: Type defaults write com.apple.Dashboard devmode YES in the terminal. Then just log off and log on, or restart your computer. Next, Activate dashboard, then drag and hold the widget while deactivating dashboard again. Voilá! Depressing the <option> key while mousing over the widget will show the close button (works in dashboard mode, too). Dragging and holding the widget while activating dashboard will put it back again. Enjoy!
