From Nov. 20-27, the week before this year's UN Climate Meetings, 350.org coordinated over a dozen major public art installations across the planet. A satellite company, DigitalGlobal documented the project from space. My favourite is this polar bear from Iceland. Look at the link for videos and photos including King Canute trying to keep the sea back in Brighton (designed by Thom Yorke and comprised of people dressed in blue plastic).
