The Talking Treee by EOS Magazine is a unique project that gives a hundred-year-old tree living in Brussels the ability to communicate emotions via social media. The tree was hooked up to a fine dust meter, ozone meter, light meter, weather station, webcam and microphone. The equipment measures the tree's living circumstances, and that information is then translated into human language.
