Painted Earth is a painting tool commissioned by the State Architect to celebrate the opening of the Galileo Reference Centre. It might result in the largest possible artwork since its canvas covers the complete surface of our planet.
The Galileo Reference Centre is an important instrument of the Galileo Navigation System, a network of 24 satellites orbiting around our planet at 23,000 km height. These satellites constantly transmit the current time. Our mobile phones use the tiny differences in travel time of these signals to position themselves.
Once the painting tool is loaded into your mobile web browser, you can begin to draw simply by walking ➝ walk fast and the lines transform into drops, stand still and the ink will begin to pool and bleed. When you go out with a group, the collaborative image is synced between devices in real-time and up to 200 people can draw simultaneously in one area.
Once a painting is complete, it stays in that area forever.
