In February 2007, London's Tower Bridge was modified to be a giant Bluetooth enabled device. Bluetooth detectors on the bridge scanned peiople crossing below 15 times per second and displayed the location of people with Bluetooth devices as bright coloured pixels on a lighting array on the bridge's upper walkway, allowing spectators to watch the movement of people along the bridge.
