The latest in surveillance: spy tires

If you think your surveillance subjects are suspicious of the eavesdropping lamps and spying alarm clock that you left as housewarming gifts, it may be time to go into true stealth mode. That can mean only one thing: a spy cam hidden inside a wall clock that looks like a tire (or "tyre," in this case).

This unobtrusive, everyday household item is equipped with a remote-controlled digital video camera and a 2.4 wireless transmitter, according to Technabob, as well as a viewing receiver. It's right out of Get Smart.

But don't fret. If this doesn't work either, there's always the robot route.
