Wow, this site is amazing. "Radio Aporee" has Google Earth-type satellite imagery of the whole world and, like Google Earth, allows you to like thumbtack certain locations. But the brilliant idea is: users can upload sounds tied to any given spot on Earth. There are currently more than 3,000 uploads, all across the globe. A lot of them are sounds of the given place. Click on the marker over the Brooklyn Bridge, for instance, and you hear a recording of the rattle and ting of its vibrating steel cables, coupled with the ghostly whoosh of passing cars - the effect is absolutely haunting. Others have chosen to upload rather more abstract representations of place, and users can also make phone calls - literally - to record messages (a lot of people have chosen literary selections) tied to any place on Earth.
It's Google Earth with an avant-garde soundtrack. Really cool.
