The clever, interactive digital billboard in East London's Westfield Stratford mall features a cute pup looking for a home. When you move, the dog moves with you.
Here's how it works -- volunteers hand people a pamphlet for Battersea Dogs and Cats Home that has a chip embedded inside and the billboard has a sensor that activates as people walk by, creating the illusion that the dog is trying to follow them home.

The ad is part of OgilvyOne's "Looking for You" campaign that's designed to promote pet adoption for the group.
