There are a lot of Widgets that owners of newer Macs with a dashboard can download to either make life easier, get info faster, or just to entertain you, whatever you are in the mood for! My favorite is Scenario Poker, a limit poker game that advances tournament style as you progress. Another cool one is Starry Night, one that shows you constellations from where you are in the world. There are also podcasts that you can get, depending on the music you like. My favorite is from Stone's Throw records.
