this is amazing! congratulations on the great work!
how does it get the radio feeds from all over the globe?
It's incredibly mind-opening, if I asked you "Do you think Timbuktu has a radio station?", you'd say "For sure.", and we could even google that term to find a website or two, but with them visualized on a globe we could just randomly browse places to listen to what the locals are listening (sadly Timbuktu doesn't seem to be on their map).
