Jewellery made from urban decay
One of Detroit's most-abundant "resources" is the graffiti which covers walls and abandoned buildings all over the city.
Where some people might see urban decay, Amy Peterson saw opportunity and today she is the co-founder of Rebel Nell - a jewellery company which turns graffiti into earrings, necklaces and cuff-links.
The company took off after winning funding from the local community at a Detroit Soup dinner, and today it employs three previously homeless women who design the jewellery which is sold in cities across the United States.
