"sub|version" by Brisbane design firm The Buchan Group
This ghostly figure could be seen haunting the waters during Vivid Sydney 2012. But it's no supernatural apparition. The ghost is, in actuality, a subaquatic light sculpture created with projection mapping, corrected for viewing near the northern Overseas Passenger Terminal tower.
"The piece is an innovative mapped water projection, and can be seen near the northern Overseas Passenger Terminal tower. The installation extends the virtual performance into the waters of the Quay itself and features elements usually found only on land, including high-contrast people and scenes submerged in symmetry with the spectators. A spotlight reveals forms, figures and patterns hidden in the depths."
