Breathing Earth (breathingearth.net) is a map of the world showing a real-time simulation of the CO2 emissions level of every country in the world, as well as each countries birth and death rates. The art is beautiful and with the sort of percussive, bugs-in-the-forest soundtrack, it keeps you staring for quite a while, watching icons burst and disappear in correspondance with the actual arrival and passing of lives around the planet.
