White Night Melbourne is an all night event that is held around the third weekend of February. It is held in various precincts in Melbourne's CBD and the city fringe.
The above photos show light projections on part of the Royal Exhibition Building located in the Carlton Gardens.
Flinders Street is one location that light projections are normally shown on tall and narrow buildings.
