Street Traveller is a blog about famous and important tourist destinations around the world. Each post looks at a different locations and mashes-up Google Maps Street View with Flickr photographs, YouTube videos and Wikipedia articles.
The Street View option for each location has a neat four-way view. Panning the larger Street View image also pans three smaller Street Views of the same location, which show views 90 degrees apart. In effect this means you can look north, east, south and west at the same time.
