At first glance this looks like a mirror, right?
Well, it’s actually a shot of the dome in the QVB building in Sydney, taken exactly below.
I love the interaction of squares, circles and colours that this space creates, viewed from this angle.
Excuse the faces!
It's So Khay 
Wow, I love the QVB but can never stand still long enough to get a good look a different angles like this. Thanks for sharing.
You should next time you go; it’s such an amazing building!
