In the middle of Africa, sitting on Lake Kivu, between the Democratic Republic of the Congo and Rwanda, you'll find a little island. This happy accident is a place where families established of Congolese and Rwandan refugees have created a unique culture. Behind canopies of pure green, their children pile into a tiny schoolhouse; marching up mud hills without the aid of shoes. Women dance and sell necklaces made out of paper beads to the few visitors brought over by tour boat. It's both a proud and humble place, and difficult to explain if you haven't seen it yourself. However, if you wanted to share these amazing visions with your friends back home, all you would have to do is pull out your iPhone and snap a Twitpic. On top of that hill, in a bright yellow kiosk, you can buy a SIM card to provide Internet to your phone.
