Actors, wearing T-shirts with the inscription SHOP/WINDOW/READING and carrying megaphones, walk along the local shopping precinct. As the stride along, they deliberately read out loud nothing but the words and messages found on the front of buildings, in the shop windows, or on the bags and clothes of pedestrians, thus alerting people's minds to the kind of information that normally works on a subconscious level. After this brief emergence, the messages fade back into the unconscious.
