This is a homemade money shredding alarm clock (previously: a conceptual one). After the alarm goes off you have ten seconds to disable it before the thing starts eating your money. I mean, provided you were actually foolish enough to put money in it in the first place. I'd just put all my credit card bills in there and then sleep through it.

Thanks to carey, who still wakes up the old fashioned way: when sunlight starts shining into the entrance of the cave.
