Why so blue? 3,000 people strip off and daub themselves in body paint as they take over Hull city centre for huge art installation

More than 3,000 people shed their clothes and painted themselves various shades of blue (left, bottom right) as they posed for a huge art installation in Hull, East Yorkshire. They caused quite a stir around the city, with hundreds lying down across a road in the city centre while others circled one of Hull's parks. And they were even more of a sight to behold when they put their clothes back on (top right).
