Flickr Time Photolayer
This is an interesting mashup of Google Maps and Flickr using the SIMILE Widgets Timeline component.
The map allows the user to view Flickr images for any location in the world. If you don't like the latest photographs for your location then you can use the time-line above the map to view Flickr photographs uploaded on different dates.
This addition of the time-line means that you can search for photographs for particular locations on specific dates, such as Washington on the day of President Obama's inauguration or Greenwich Park on the day of the London Marathon.
