The Color the Bridge project, part of the annual Vivid Sydney light festival, lights up the Sydney Harbor Bridge with 3200 programmed LED lights and fiber optics, giving the otherwise gray concrete-and-steel structure a totally different appearance.
Better still, the project lets you design your own sequence for the LEDs and watch it play out across the bridge! Alas, you can only do this if you can get to the bridge between now and June 10.
