“I need to be a hamster!” Robyn yells across a packed hall. Here, at the kick-off of Tekla, the free one-day tech conference that the Swedish pop star has helped organize for 200 teenage girls, she is merely a hamster seeking her other hamsters. As an ice-breaking exercise, the girls have been divided up into animal groups and tasked with creating a new noise that their animal (or jellyfish) makes. Robyn joins the hamsters and they studiously discuss how it should sound; minutes later the room is an orchestra of shrieks, caws and stamped feet.
