Flickr and Google street view mashup - New York Public Library

For the background story to this please read my blog post.

This uses the Flickr API to create a KML file from the Changing New York, 1935-1938 set of photos from the New York Public Library Flickr commons collection and merges it with the Google maps and the Google maps street view. Click on a marker, and if the location is available on Google maps street view, you can instantly compare the historical and contemporary images.
