Shortly after 16-year-old Preston Fosback and his mother displayed a Barack Obama sign in the front yard of their Oregon home, it was stolen. So was the replacement one they displayed. So Fosback handmade a third one - but this time trained a video camera on the sign, to watch for thieves. Which is why you can now watch live streaming footage of the Fosbacks' yard sign on the internet.
The website, featuring a chatroom, has become host to an international community of sign-watchers, who discuss politics and type "car!" or "school bus!" or "truck!" when vehicles pass by.
