On the 25th revolutionary 1st of May demonstration in Berlin-Kreuzberg in 2012, protesters were throwing huge inflatable cobblestones, made of silver-reflective foil and tape. The creative intervention meant as a celebration of an object which is both a symbol and a material weapon of anti-authoritarian struggle everywhere. It also aimed to bring new strategies of tactical frivolity into the demonstration.
The campaign was initiated by the art-activist collective »Eclectic Electric Collective« (EEC), an international organised network, consisting of artists, activists and other interested people, with a base in Berlin. The collective now operates under the name Tools for Action.
