A picture is worth a thousand words. How about a picture that is 80 Giga Pixels and is claimed to be the largest 360 panorama image ever created? This gigantic panorama has been created by Jeffrey Martin and captures a very large part of the city of London.
The panorama is hosted at 360Cities and provides a great opportunity to tour the city of London without leaving your couch. The best way to enjoy the image is to click on the start tour button which will then take you through different parts of the city allowing you to enjoy several landmarks and monuments. On the other hand, if landmarks are what interest you, you can also click on the landmarks button which will display a thumbnail list of around 15 different landmarks in the city of London. Clicking on any of the thumbnails will then take the image to that exact location.
You can also use the mouse arrows to move around and zoom-in and zoom-out to a great degree. The quality and clarity of the image is pretty decent even at the most detailed level. 360Cities also has panraomas from other major cities of the world giving you a 360 degree tour right from your desktop.
