Regards Alchemy arrows, I asked the curator of the gallery today if they signified anything in particular. The short answer was Bret was very much into the idea of 'tension' and opposing thoughts & philosophies. The guy had a lot more to say, but I couldn't soak it all in! The Alchemy artwork is truly amazing in real life and extremely 3D, there are things 'popping' out and behind everywhere. Worth a visit if you're in Sydney sometime.
Although they have a strict no photos policy, the guy was sympathetic to my holding the Love Over Gold single, and let me take one
On fb, on the MK fans page, if anyone's interested.
