Worldwide Webcams Maps
Mashed World has created a number of webcam Google Maps for different countries around the world. The webcams for each map are provided by webcams.travel, who recently had a layer added to Google Maps.
When you roll over one of the webcam map markers on the map a thumbnail appears showing the latest image from the webcam. Clicking on a webcam marker opens an information window with a link to that webcams page at webcams.travel.
