In the summer of 2021, a total of one hundred multidisciplinary, artistic-creative interventions took place in Dortmund under the title Jahr100Sommer. Things, images, musicians and artists appeared and disappeared again. The city was transformed into a space of art and experience. The result is a visual identity to take along. Cubes can be easily transported as stools, tables or decoration, flags mark the event from afar. The bright yellow, as well as the round and angular dots stand out from the urban space. Elena Schneider’s Konsole nestles to the geometric design language. In addition, an extensive documentation has been created.
