mr_lithic writes "The artist Richard Box has used the electromagnetic field generated by overhead transmission cables to power 1300 fluorescent lightbulbs positioned underneath. Some pictures available. Professor Denis Harshaw at Bristol University explains "There's an interactive element to all this, too, for those who go to the site itself. 'You affect the lights by your proximity', explains Richard Box, 'because you're a much better conductor than a glass tube. And there's sound as well as light - a crackling that corresponds to the flashing of the lights. There's a certain smell too, and your hair stands slightly on end.'" Sounds cool and it is on until February 29th. Directons here."
