Recently, Sony had their balls cascading down through the electronic panels on the escalators at Tottenham Court Road Tube station. Soon many other poster sites on the underground will show moving images. Already Bluetooth technology will let posters interact with your mobiles, as in the sci-fi movie Minority Report.
In New York's Times Square, a Dove poster asks passers-by to vote by phone on whether the old lady shown is wrinkled or beautiful. The votes ping up on the poster itself.
Now the Leo Burnett agency has constructed a poster for McDonald's that's got Chicago talking. It's a sundial.
