Suppose for one reason or another you needed an image of a person who looked like a horse. Searching Google Images would take hours, but a new extension for Firefox and IE called Polar Rose would make it a snap. A page loads, the extension looks for faces and, if identified already, provides the information to the user. If unidentified, the user has the option to add an ID. It's in beta, but over 160,000 faces have been identified. Is yours one?
