Refresh Dashboard Widgets: Command+R Sends a Widget into a Whirlpool
Mac OS X has a fancy way of refreshing your Dashboard widgets. It’s better watched than described or shown in pictures, so open up Dashboard, click on any widget, then hit Command+R and watch the widget disappear and reappear into a twirl.
The larger and more colorful the widget the better the effect, and you can hit command+R repeatedly if you feel like showing this off to someone else. Other than refreshing a widget, which rarely needs to happen, this isn’t too useful, but it’s great eye candy.
