In April 2015, Nike released its revolutionary kinetic digital art project, Force of Nature, for the Nike Innovation Summit at Truman Brewery in London. The work was created in collaboration with Field, a London-based design studio. By stepping onto a treadmill and beginning to create movement, the participating runner is presented with a fluctuating shower of stunning, multicolored sparks, similar to an energy “mirror” of themselves, created by the movement put forth by him or her on the treadmill. The flux of lights is meant to imitate the runner’s motion and turn the human body into a digital art piece. . The work recalls earlier artworks, including Nancy Paterson's Bicycle TV (1989) and Jeffery Shaw's Legible City (1989-91), both of which used a bicycle as the interface by which the user's activity generates an animated video environment.
