Emerging technologies of interaction and the changing nature of audience engagement present a radical challenge to Western narrative art in both its vehicles and traditions. Boundaries between established media forms (i.e. games and cinema) are thrown into question and the very concept of creative authorship problematised. In this context, Hosts explored the creative potential of interactive art and narrative forms in a site-specific 'free' public space. This project focused on new forms of public mobile art, where interaction has become 'untied' and spatialised (mapped onto real places or geographies).
