Bill Fontana's Speeds of Time is a real-time sculptural sound map derived from the sounds of Big Ben. A network of microphones starts at the House of Commons from the bell tower itself, spreading out to rooftops and terraces around and beyond Parliament Square. As it does so, Speeds of Time traces the contours of the temporal deformation of the bells. Some of the microphone locations include Westminster Abbey, the Treasury Building and the Horse Guards Clock at Whitehall.
