Sylvia Winkler (*1969/Austria) and Stephan Köperl (*1966/FRG) are visual artists based in Stuttgart/Germany.
Since 1997 they have been realizing projects together. The main part of their artistic activities focusses on site- and context specific interventions and videos, which they realize in various places around the globe. E.g. about the electoral system of Indonesia, a Korean Smart City or the everlasting planning process of a house for film and media in Stuttgart. Their projects usually develop from observations and research on the spot and are implemented temporarily. Sylvia and Stephan have exhibited worldwide and have contributed to numerous international filmfestivals.
