Well duh Nasha, They said they got the idea from the books
And I doubt it will be an actual clock, maybe a frame ont he wall maybe, but I think it wont become succesful, if you need to know where someone is you just call them and ask
If theyre in trouble they dial 911, If they go missing for x ammount of days the GPS in most phones tells police where they were in the past x days
More than likely its just for publicity
Edit: Next thing you know were going to have moving picture frames, News Papers that have videos on them, and things you hold in your hand that make things do stuff from far away
Oh wait, we do lol
