Is it possible to have an alarm that requires you to shake the N900 for say 5 seconds or so before it will snooze/switch off?

There are so many alarms on the market these days that MAKE you get up I figure this could be a good one for phones as a lot of people use there phones as alarms.

Nothing vigorous of course, just a light shake that wouldn't cause any damage to components but would require effort for you to stop it.
