This looks like a spectacular piece at Hobart's current Dark MOFO.
A large scale public piece that creates a 15km tower of light made up of 49 searchlights to break the black evening.
This is Spectra, Ryoki Ikeda's installation that forms the central plank of Beam in Thine Own Eye, and the word is people seemed pulled towards it unable to resist its allure.

Grand Sculpture Light and steel in Melbourne Fed Square
The Helix Tree by Bruce Ramus is a grand sculpture of light and steel in the centre of Melbourne City at Fed Square. Inspired by the naturally occurring shape of the helix, the sculpture is constructed from 21 curved steel beams fitted with hundreds of LED lights. Like branches of a tree, the beams spiral 13 metres high into the sky from a central trunk. The Helix Tree uses sound-responsive technology via which voices of Melbourne bring to life its unique and vivid light displays.
