Initiated in 2005, sidewalkCINEMA was an interdisciplinary project combining spatial intervention into urban contexts and open-air film festival. After a public invitation in 2005 and taking up the focal theme urban phenomena chosen by WOLKE 7 for 2006, a number of “viewing stations” were established along Kaiserstraße in Vienna’s seventh district in the context of the project’s third round in 2007. These stations were to encourage people to stay, to become aware of their surroundings, and to communicate on public space in the daytime. In the evening, the “viewing stations” turned into public cinema spots: shorts, animation films, but also experimental works and documentaries on the issue of city systems were projected on shop windows from within and, thus, into public space. As the organizers had deliberately decided against a closed cinema space, a larger public could be offered an opportunity to enter into a dialogue on urban questions in an innovative manner according to the focal theme “city system/s” agreed on by WOLKE 7 for that year.
