Isobar Mobile and Posterscope have unveiled a film noir inspired campaign, featuring Frank the ‘private eye’, displayed at 300 high-profile sites in London and Manchester.

Each poster features a QR code or URL call-to-action, pushing consumers to a purpose built HTML5 site. They then see a short graphic novella noir featuring Frank, who guides them through various rich interactions on the handset browser.

The application then asks users to connect to Facebook, pulling in pictures of the target of their desire and using an algorithm specially created by Isobar Mobile to find whether the object of their affection loves them or not.

Users are left with a scene of either their beloved walking off into a moody sunset a picture in a smashed frame that the user can then share to Facebook.

Tim Dunn, director of strategy at Isobar Mobile, said: “We wanted to pull together a number of strands of our thinking with this campaign, wrap them into a creative execution that will both intrigue and delight the public, and allow our team to have a bit of fun doing something purely creative.

“Mobile is hugely underused in its creative capacity, and as a creative agency that specializes in design and build of high-end customer experiences, it’s been a fantastic opportunity working with Posterscope and the various media owners (JCDdecaux, Clear Channel and Hi-Tech) to showcase the potential of how mobile can be implemented to bring consumers and brands closer together.”
