The Puzzle Alarm Clock
February 1st, 2007 
Some alarm clock just can’t wake you up in the morning but not this, the Puzzle alarm clock. It features four piece of puzzle on top which will automatically reject once the alarm rings and you will need to put those four pieces back together to stop the ringing. It is powered by two AA batteries and it is a available for $59.

I got this for $20 on E-bay and it’s still overpriced. It works as advertised, but its a 3″ cube, very small, very cheap, not worth $20.
