I've just realised a model of the Darling Park Towers that I've published a couple of months ago is active in the 3D Buildings layer in Google Earth (see picture). It's a bit lame, but I've put it together in less than one hour during a not-so-interesting session at Wherecamp 2008.
You can check it out by running Google Earth Client and searching for "Darling Park" or "-33.872194,151.20314". Both should take you to Sydney's Darling Harbour (don't forget to enable the 3D Buildings Layer). Those three triangular-prismatic buildings are the Darling Park Towers, home to Google's Sydney offices.
By the way, anyone can upload building models to Google's 3D Warehouse. Learn how to do it here.
