So let’s say it’s 3 AM, and you’ve got an important meeting in, oh, 6 hours, and you don’t quite trust yourself to wake up when the alarm goes off.
Voila. An AppleScript that will bide its time for a while, and then will tell you loudly, over and over, to get your ass out of bed. The voice changes randomly to prevent you from somnambulantly acclimating to it before the higher brain functions kick in.
I think this would be all the more effective if, after a few minutes of inaction on your part, the voices would begin to overlap so you had a crowd of people telling you to get a move on.
