It's loud, it's infuriating, it's ... clocky
"He knows when you're sleeping, he knows when you're awake; Clocky, the alarm clock that runs away and hides to get you out of bed." Everybody knew somebody like this in college: the guy who would hit snooze seventeen times before waking up in the morning; who finally had to put his alarm clock in the bathroom so he'd have to get out of bed to turn it off. Looks like somebody out there with some engineering smarts had this problem too, and did something about it.
Clocky works like this: if you hit snooze after its alarm goes off, it'll jump off your nightstand and wheel around the room looking for a place to hide before it goes off again. It'll find a slightly different place each time, so you always have to go searching for it. Devilish, no? What's more, the alarm is an ear-splitting 80 decibels (any louder than that is considered potentially damaging to one's hearing.) And the release of Clocky at holiday-time makes it the perfect stocking-stuffer for that insufferably lazy layabout on your list.
