Macquarie St in central Sydney has a string of beautiful colonial buildings along it. For the past two weeks, up until Christmas night, someof these buildings have been lit each night with this wonderful array of designs. These are a few. [I don't have a tripod, so forgive me where some are a bit blurry]
These photos compement the one at Sydney Daily Photo.
