To celebrate the 25th anniversary of the fall of the Berlin Wall, light artist Christopher Bauder and his brother Marc were commissioned to create an extraordinary light installation called LICHTGRENZE (Border of Lights). From the 7th to the 9th of November 2014 the 15.3-kilometer frontier that once divided the city center was re-imagined in light by 8000 balloon lights all developed and produced by WHITEvoid. More than 1 Million people was taking part in the choreographed and televised balloon release event in the streets of Berlin on the last day of the installation.
