Paint it green

The UK's longest graffiti mural has been painted on to the building-site hoardings surrounding a new environmentally sustainable student-accommodation development. Street artist Mohammed Ali spent three days creating the 428m long painting at the University of Bradford. Mr Ali's work fuses graffiti art with the Islamic calligraphic tradition. The work, Life in the Wall, incorporates quotes from activists and public figures on themes such as unity, positive change and the environment.
