Shake N Wake Alarm Clock
November 20th, 2009 
This Shake N Wake Alarm Clock is a wearable alarm clock that is going to wake you up by shaking and vibrating. Just strap it on your wrist or place under your pillow before you go to sleep. The alarm clock also features an optional beep alarm so you can use it as a normal alarm clock. It also has a backlit LED display so you can check the time when you are in the dark. The Shake N Wake Alarm Clock will cost you around $25. I think they need a better pic.

I have a timex watch with an alarm that vibrates instead of making noise. It was about 20 dollars and it looked liked a normal watch, not a kitchen timer!
It’s a great idea but the watch is a little bit big.
