The "Celebrating Flows" concept developed by Licht Kunst Licht is based on a single assumption: light is associated with positive values; so, rather than emphasizing problematic environmental issues, Licht Kunst Licht worked to improve awareness of nature and sustainability and thereby develop good and positive solutions. Starting from an analysis of the cities where it operates, Licht Kunst Licht chose Berlin because, as the Mayor of the City, Klaus Wowereit, once said, "Berlin is poor but sexy". The city's charm derives from overlapping time, nature and freedom and, based on these aspects, they identified the site for an installation: Oberbaumbrücke - a bridge that embodies the intersection of these three elements to the full. In particular, inspired by movement and the sense of flowing, they focused on the element air. The idea was to set up a canvas to project the gobos by creating a layer of fog: the combination of air and fog gave shape to the installation itself.

The air element is expressed as the movement of a fabric in the wind or as a graphic element inspired by nature, as a volume with details of the clouds, as colors with the projection of a sunset or as filtered and geometric light.

Light Bureau put forward a concept based specifically on the topic of climate change, seen both as a realdanger as well as denied by certain members of society; the very fact that it is such a divisive topic makes it all the more interesting. The study identified the four elements - earth, fire, water and air - as the key points in the ecological balance and the foundation for all living species, depicting them in their harshest versions should humanity continue to ignore Climate Change: earth will become merely bare rock because the increase in greenhouse gases will eliminate plants and animals from the surface of the planet; water will take the shape of a tsunami; air will increasingly generate hurricanes; flames will catch fire so easily because of the aridity caused by higher temperatures.

Focusing attention on these 4 basic elements, turning them into the protagonists underlying the concept behind the gobo collection, seeks to raise awareness of the phenomenon that is rapidly transforming our entire planet.

Light for Future involves some of the town's most significant locations - the Cloister of Sant'Agostino, the Cloister of Palazzo Venieri, the Civic Aqueduct, Porta San Filippo, the Multisala Sabbatini and the Convent of the Poor Clares -, stages for architectural and creative light installations (described along the way by information panels and the Light for Future app) using high-efficiency luminaires and perfectly integrated into the environments thanks to the minimal, compact design.
