Commercialisation of the street-urban space is nothing new – visual narcotics sticker in O’Hare above, and a gallery paying homage to/ripping off (mostly) Banksy graffiti in Brighton below.

How does this space play out when combined with: technologies such as QR bar codes, RFID and more sophisticated image/shape recognition; and the ability to make real time micro-payments?

Forget big ad campaigns and 20 meter bill boards – the highly contextual niches of the physical world is where its at. Or at least until gestures, actions and emotions can be turned into search strings and macros.

To what extent is this already here? DHL barcoded sticker on the inside of a bank window – also from Brighton.
