Flags and banners have been used for centuries for optical communication. They transmit messages (e.g. shipping) and stand symbolically for certain group affiliations (associations, countries, gender etc.). For the project, numerous unused masts were reactivated and connected to a course around Scharmützel- and Storkower See in the lake district Oder-Spree. 27 + 1 artists from the 27 EU member states and the transitional state Great Britain were invited to design individual flags. The individual flags can be understood as an image, as a game with identity, as an intellectual engagement with sign systems or as an object.
