Through the CentreForSydney we have a nice animation illustrating many of the ideas in Clover Moore's Sydney 2030 vision. The animation (good work Jack) zips around the city showing schematically the evolution of various parts of the city proposed, including Circular Quay, George st, Central Station and Darling Harbour.

The SMH Article ahead of talk by consultant Architect Jan Gehl has the vids as well.
