I finally got around to updating one of my API v2 maps to v3 of the Google Maps API. Video Map is a Google Map of over 700 videos of landmarks around the world.
All you have to do is click on a marker on the map and you can then watch a YouTube video filmed at the selected location. After watching a video just use the 'Zoom Out' button to return to the world map view.
The data for the map is a few years old now so there might be a few deleted videos in the collection.
