Mods don't get much simpler and more useful than this: It's an alarm clock that whisks open some window blinds when the alarm goes off, so the sun can tempt you out of bed. There's a microcontroller to handle detecting the alarm signal and to drive a servo wired into the blinds, and some switches to override the alarm and open or close the blinds on command. Check the video of it in action.
Looks great, but frankly you'd need to wire a giant servo to my feet to drag me out of bed rather than use hack like this, but YMMV. [Hackaday]
