In the workshop held by  Paolo Bonelli , author of  CoScienza Ambientale , the voice of nature is transformed into "sensitive" data through an impressive set of self-buildable tools, put online and kept active as a method of digital activism, which can make us hear the voice of Gaia before it explodes and help us understand its arguments. Geiger sensors, fine dust sensors, acidity sensors, rain gauges, landslide sensors and many others, all rigorously addressed and buildable with little money, connect to a large civic-network of conscience. The two-day workshop will involve the participating artists and geeks in making these data sensitive in an effective, poetic and proper way of our time.
