Tunisia: Youth express themselves through graffiti

From football rows to images of love and affection, a variety of messages find embodiment on Tunisian walls. People of various ages and social classes dedicate effort and money to turn the walls of Tunis into a random mosaic of letters and figures, understandable only to their peers. 'I find a space where I can move around with my black lines, away from the eyes of censors, to write whatever I want,' said Semer Idoudi, a 20-year-old student.
