The clock that makes you wake up

As someone who generally snaps awake to his alarm, I always find gimmicky alarm clocks amusing. I think I posted about one that actually rolls away from you when it goes off, but this one is also fun - you have to assemble four puzzle pieces in order to disengage the alarm. Given the studies about mental capacity immediately after sleep, I don't think even a four-piece puzzle will feel amusing when waking to the sounds of the latest public radio pledge drive.
