We have always liked the panoramas over at Everyscape and now they have launch as new high res viewer along with coverage of Christchurch in New Zealand thanks to the nice people over at ZNO. The new viewer includes a full-screen option and zoom functionality, which creates a fully immersive user experience, allowing users to explore Christchurch streets and businesses as though they were there in person.
Of note is the inclusion of interiors and the nice transition between scenes - take a tour at http://www.everyscape.com/index.nz.aspx. We are now intrigued as to who is doing London, or come to think of it most of Europe which we assuming is coming soon.
