On the occasion of “Notte Bianca 2014” (overnight arts presented by Municipality of Florence), several art installations have been commissioned to artists. One of the most impressive is #River of Light 5 by the award-winning Creatmosphere. The UK artistic studio was founded in 2003 by French light artist Laurent Louyer and focuses on the exploration of “light in situ”. The studio places the context of each project at the heart of the creative process, working on different “urban lightscapes” within the city fabric and giving resonance to architecture and public spaces. Creatmosphere has played with light and water in numerous projects exploring the identities of cities in relation to historical water infrastructures, bringing awareness about water’s fundamental role in Nature and other related environmental issues. The series #River of Light is a touring installation that combines light, sound, and new technologies to celebrate the rivers of the world. #River of Light 5 was a dynamic installation on the River Arno by the famous Ponte Vecchio in Florence. The project consisted of 24 large light spheres that floated on and above the water, responding to the flow of the River Arno and the wind flow.
