here's the description of the show... do a search on the yamakasi (I was close) if you want to learn more I suppose.

HOT DOCS - YAMAKASI
For more than 10 years the Yamakasi have defied the laws of gravity; climbing walls, leaping between buildings and creating a new athletic code rooted in discipline, self sacrifice and physical endurance. They transform their oppressive concrete environment into one of fantasy, possibility and play. The men share the values of friendship, honesty, humility and courage as they discover their weaknesses and learn to overcome them. (From France, in French, with English subtitles) (Documentary)
