Here's a funny little gadget that helps the most gadget-addicted of us to put the cell phone away for an enforced break. It's the Cell Lock-Up, which has a timer you can set for locking your devices away for that amount of time. And if you try to get at your cell phone before the allotted time, a buzzer sounds.
The Cell Lock-Up retails for $20 (I couldn't imagine spending any more than that on this) and probably makes a better joke gift than anything else. Though then again, with so many kids and teens burying their noses in their cell phones rather than their homework or, heaven forbid, conversations with people standing in front of them, it might be a good idea for parents to have this set up for mandatory look-up-at-the-world time.
