Local Lingual is a cool interactive language map. Click on any location in the world, and it plays recordings of the local language, along with the national anthem and other info.
You can read more about it at Google Maps Mania.
I’m adding it to The Best “Language Maps”
ADDENDUM: Here is a comment left by a reader: “Neat idea, unfortunately, many have used it for making inappropriate recordings. Use with caution — many of the records contain language that is not appropriate for children/schools.”
