On display in the British Library, as part of the Growing Knowledge Exhibition, the meters reside on the wall next to the Microsoft Touch Table. Detailing the level of tweeting in 9 cities (San Francisco, New York, London, Moscow, Shanghai, Tokyo, Hong Kong, Sydney and New Delhi) around the world the exhibition is well worth a look, its free and runs until 16th July 2011.
Thanks go to Ben and Steve of CASA here at The Bartlett, University College London, for their work on the project, we are biased, but its outstanding.
You can see the digital Tweet-o-Meters here.
