I think almost every visitor to Sydney spends some time at Darling Harbour and they have kids they always stop by the spiral fountain. Kids just love playing there and getting a bit wet, especially on hot summer day.
For me as a photographer this is an endless supply of abstracts. Different light conditions expose various patterns in watter of the little steps, or you can concentrate of water surfaces. Today I have noticed wind was creating lines in water at an angle to the steps of the fountain.
