Particle Falls
Particle Falls is the work of artists Andrea Polli and Chuck Varga, which visualises real-time small particulate matter air pollution (PM 2.5) in downtown San Jose via the changing scale of a laser light cascade on the side of a city building. The work is made possible through the AirNow project which shares live air pollution data throughout the US. It aims to raise awareness amogst the public of air pollution and thereby encourage behavioural change. The piece is also accompanied by a real time web visualisation.
