OK forget Banksy, graffiti has been on the cultural agenda ever since Pentagram co-founder Mervyn Kurlansky's 1974 Watching my Name go By, a book about graffiti on New York subway carriages. It doesn't count as cultural agenda, of course, when the graffiti is on your latest building. But here's an extraordinary movie, Muto . An animated graffito, it starts with a tracking shot along a graffiti-covered brick wall.

The artist Blu is based in Bologna and is currently showing at Tate Modern on London's South Bank in the Big Art Mob Show. Take a look at his website .
