To commemorate the 25th anniversary of the fall of the Berlin Wall , artists Christopher and Marc Bauder have, along with the studio Whitevoid, reconstituted fifteen kilometers of the original route of the Wall with some 8,000 light balloons filled with helium. This project entitled “Lichtgrenze”, “Border of Light” will be installed on November 7, balloons will fly the 9th of November at night. A nice way to remind people of Berlin, a crucial part of their history.
