We take a look at a new season of art and exhibitions as Stockholm's "Youseum" offers influencers and selfie enthusiasts a temple for the 21st century's favourite form of self-expression. Meanwhile, a museum in the French city of Rouen says "please do touch the art", as a new show encourages a sensory experience of sculptures on show. Plus, visitors to the Quai Branly in Paris get a chance to plunge themselves into Bamiléké society, with traditional ritual objects and artefacts on display thanks to a Franco-Cameroonian partnership.
