Following up on YouTube's April Fool's Day prank, Google has launched one of its own. It's similar to its prank last year, when it launched an awesome 8-bit version of its Maps service. This year, Google has transformed Google Maps into a treasure map. In order to access the map, all you have to do is click on "Treasure Mode" on the top right of the Google Maps page. Then you can watch as your location is magically transformed into a treasure map.
