Imagine looking down on your wrist and it immediately lights up and shows you the time and date and some notification that you have messages. Rotate your wrist clockwise and you can see some more details about the message (the subject, who it's from, etc.) and you can decide whether you want to take out your phone or tablet and address it.

Rotate your wrist counter-clockwise and you see slowly start to see more relevant information (weather, news headlines, etc.). It would be kind of like google now, except not necessarily requiring interaction and it would be much more visually interesting.
