It sounds odd to invite people to scrawl over the walls of a picturesque Tunisian village. The island of Djerba - known as 'Island of Dreams' - has invited 150 international artists to take part in the street art project Djerbahood, curated by Tunisian-French artist Mehdi Ben Cheikh. In July and August 2014, artists from about 30 nations travelled to Erriadh to create murals. One of the oldest villages in Tunisia, it has become host to one of the biggest meetings of the modern street art scene.
