The Sydney Harbour Bridge is illuminated for the festival. The lighting display is designed by 32 Hundred Lighting and uses a satellite-navigational grid to coordinate lighting changes; as vessels adorned with brilliant LED lighting pass through parts of the grid, colours change simultaneously -- and each little vessel becomes part of a coordinated display that moves across the colour spectrum as they move across the harbour.

Light installation entitled ‘Fugu’ piques a visitor’s interest. Artists amigo and amigo were fascinated by the pufferfish and its unique form-changing abilities, exploring this unique skill within their work. They created ‘Fugu’ as a kinetic lighting sculpture, which captivates audiences by expanding and contracting its spiky rotating form. As visitors gather, Fugu comes to life, his swirling body expanding, glowing and pulsating in colours inspired by the sea and the astonishing creatures living beneath its depths.

A man stands with the light display called ‘1,000 Cranes’ created by Ambient & Co. The display is inspired by an ancient Japanese legend: if a group of 1000 origami cranes (known in Japanese as senbazuru) are hung in one’s home it will act as a powerful and benevolent charm and bring good luck.
