Public Ad Campaign, an organization that is opposed to outdoor advertising, has created an augmented reality mobile app that replaces the billboards in Time Square with artwork (see the app in action at a recent public beta test). Public Ad Campaign and collaborator The Heavy Projects hope to expand the app in order to takeover billboards in other public spaces.

This is a great idea but the irony is advertisers will use the same technology to surround us all with bepsoke adverts!
