These mini protesters have popped up all over the Southbank Centre, on stairwells and signs, hanging round the bars and box office, and in all kinds of little nooks and crannies. Over the weekend, visitors were asked to write a short manifesto on a piece of paper; those declarations are now carried on placards by these little plastic people and range from pleas for less homework to serious and funny suggestions for making the world a better place. They'll be there until the London Literature Festival ends on 13 October so you've a week to get hunting — and let us know your favourite in the comments.
