Retrieved 23 June 2022, from https://twitter.com/connectedtree One of the first 'Twittering Trees' is Swedish telecommunications company Ericsson's Connected Tree (@connectedtree). The tree, which first went on show at the 2010 Mobile World Congress in Barcelona, senses changes in the surrounding electromagnetic field and responds by tweeting. It also reacts to movement by playing music, speaking and turning on and off lights.Connected Tree's account hasn't tweeted since January 2018, and the tree's current Twitter location is 'in Sweden on vacation'.
