Information decoration on a city scale. Every night from the 22 to the 29 of February 2008, the vapor 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 neon-style graph.
