Along the former Berlin Wall, people have been creating a dense collection of con/temporary cultural use-scenarios in a number of common and shared spaces. We are facing great potentials to involve ordinary citizens like you and me in processes of change, unleashing unknown energies. Established structures and institutions are in crisis. They are trying to hold on to principles that have already failed. But crisis gives birth to hidden and undiscovered potentials. Therefore, we invite you to join a crowd of determination and chaos. Let us form a movement that connects forces from different directions: initiatives, clubs, enterprises, and all over this: citizens. What we are looking for is a shared effort in research and deed, a third culture, so to say.
