Vivid Sydney is an annual festival of lights, music and more. All through the city light displays could be seen, some were truly amazing (my favourite was the story like display on the facade of the Customs House) and some were interactive fun little gadgets (like the drums that simulated fireworks display on trees near The Star). You could definitely spend a couple of hours walking along the city, following the lights and photographing: from Circular Quay and Opera House, to The Rocks, Walsh Bay, Darling Harbour, Pyrmont and even the University of Sydney.
We found it lots of fun, especially as this was our first year! Here are some pictures of the event:
