It might sound French but it's going to happen in Finland. Every night from the 22 to the 29 of February 2008 the vapour emissions of he Salmisaari power plant in Helsinki will be illuminated to show the current levels of electricity consumption by local residents. A laser ray will trace the cloud during the night time and turn it into a city scale neon sign.
Nuage Vert is a part of Pollstream series, an artistic intervention in environmental ethics by HeHe (Helen Evans and Heiko Hansen). This terrible beauty is presented by the Pixelache Festival of Electronic Art and Subcultures.
