Two of the three are sculptures.
In the foreground is Matthew Harding's stainless steel sculpture Centripetal. His statement quotes from Albert Einstein (apparently); "When you look at yourself from a universal standpoint, something inside always reminds or informs you tha there are bigger and better things to worry about".
I do wonder how many famous sayings were actually said by the people that they're ascribed to. You know that Captain Kirk apparently never said "Beam me up, Scotty", right? Regardless, it's an interesting looking sculpture that makes you perhaps ponder for a moment on a certain interconnectedness through the universe with no single point truly at its centre.
In the background to the left is Tomas Misura's Splash, seen in images 11921 and 11934.
The two to the left of that are not, in fact, sculptures. Give yourself a pat on the back if you picked that. But I thought that they added balance to the image anyway.
Bondi Beach can be seen in the background.
