Woices--Share interesting sounds

I just stumbled upon Woices http://woices.com/ which is free internet service that allows people to create, share and consume echoes. Echoes are audio recordings that are linked to a very specific geographical location or real-world object. Woices ultimate goal is to extend reality by creating a new layer of audio information, what the creators of the site call the echoesphere, that will make the world a more interesting place. I will introduce this concept to my new literacies and media course this Fall.
