We produced 3 banner/posters, suspended over the reception desk; each will be a slogan. i.e ‘All information will be common’, ‘Advertising For All; Or For Nobody At All; Reclaim Public Opinion’ and 'Borders are for crossing'. We also propose the inclusion of Public Kiosk which is a machine for opinion formation. By taking away all retail aspects of the kiosk and replacing its branding and advertising with opinions/beliefs garnered from visitors to the Common Ground event we drew out its full social potential. ( see field notes by Roxana Morosanu). People published their opinions in and on the kiosk throughout the day. The Public Kiosk is a support structure to present our hypothesis of art and the public sphere, we announced this through graphics on/in the kiosk. Helena Hunter from the Tate Learning department joined us as part of our developmental talks on a collaborative research project between the artist - researchers and the TATE Learning Department which is concerned with rethinking the evaluation of participatory art projects. Dr. Roxana Morosanu, sociologist and research assistant RCA, joined us and produced a series of field notes.
