Daredevils are not the only ones using bridges for fun: musicians are getting in on the act too. Di Mainstone and her team at Queen Mary University of London are attaching people clad in a special body suit to architectural structures with strings that tap into a building's vibrations and can be played like an electronic harp.
Mainstone was inspired by the Brooklyn Bridge while living in New York. "I wondered whether there was a way to capture the vibrations that go through cables triggered by walking, traffic and wind," she says. Since the vibrations aren't audible, they need to be transformed into a form we can hear.
