“The People’s Smart Sculpture" – Social Art in European Spaces fosters participative art and collaborative urban art&culture processes in Europe´s cross-cultural city spaces. It´s constituted through 11 sub-projects in eight European countries and concomitant exhibitions and workshops. The approach is on two levels: the implementation of cultural participation projects and the evaluation of these activities in a cross-cultural comparative analysis and for to the aspect of real transferability. The goal of the project is a “smart sculpture” designed by European citizens which profit from the interplay of culturally different approaches.Participation has a long cultural tradition in Europe. The rising complexity of live in today’s urbanity, the cultural design of our cities, and the multidisciplinarity of urban art are based on the cooperation between different social groups, spheres of action and institutions. Citizens of any age and background, artists, cultural activists, designers, scientists and even digital eccentrics work together in designing their cultural urban environment. Not getting involved in it would be like suddenly giving up breathing – simply impossible. It doesn`t matter what influences most of us to get designers or co-designers, if it is the personal experience from 3D, net-art, hybrid art, gaming, street art, social community platforms or the general interest in issues of society, policy, decision-making. It´s about the re-design and the cultural new construction of spaces as cultural space, created by real people. Within this engagement, our surroundings appear to oscillate and change. City spaces can get ambiguous, they can be interpreted in any number of different ways, and they only loose their ambiguity when a certain cultural context corresponds with individual or social intentions. Then they can become performative spaces and environments. They can invite and include people even outside the process of their cultural re-design.
