Just seen this new ad for the second time O2 during the Grand Prix today.
I really like it.
A bubble is flying through a cityscape and various place, turning into lots of bubbles; with some music that sounds a little like Aphex Twin or Autechre.
Edit: Apparently its 'Utopia' by Jackson and his computer band. Thanks anonymous informant!
The bubbles bounce off things and cause ripples and other movement on the objects.
What I only noticed on the second viewing is that when flying over the city you see keyboard keys below, when the building ripples it looks like a film strip, and so on.
Whether it will connect with the customer is to be seen, but as a nicely understated and watchable ad its great.
