This may sound boring...but this is a great example of a real-time, global, and interactive web map - in this case showing the location, speed, and direction of all marine traffic (boats, ferries, tankers, etc.). Click on the icon to see information about the vessel and a picture. A great place to explore is the English Channel or the area around busy ports such as Hong Kong.
