Here's a Mac example. Sometimes I keep an iCal alarm alert dialog box open for long periods of time -- I know, not a great habit, but when I'm focused on programming, I just kind of push it off to the side. At a regular interval (every 10 minutes perhaps? just a guess), it steals the focus and moves to the top of the window stack. If the purpose is to re-remind me of an overdue alarm, shaking the dialog box or playing a sound would be better because I can mentally make note of it and keep working vs. having to re-click in my editor, for example, and retype whichever keystrokes disappeared into the iCal alarm abyss.
