Kongens Nytorv - København
Using the new Street View imagery for Copenhagen microformats.dk has created a really cool tour of Copenhagen. The mashup synchronises the Google Earth browser plugin with Street View to show you 360 degree panoramas in both Street View and Google Earth.
The tour works particularly well because of the extensive 3D buildings available in Google Earth for Copenhagen. To view a location just click on the Google Map. The tour then zooms in on that location in the Google Earth plugin and automatically rotates around the view. A Street View embed also rotates giving you the same view but as seen from the ground.
