The show’s name too, ‘No Spectators’, is as much an invitation as it is a maxim for visitors. Atkinson wants you to get involved, neatly circling back to one of the festival’s Ten Principles: participation. In one room, Shrumen Lumen (2016), an interactive Wonderland-esque installation of five towering origami mushrooms by art and design collective FoldHaus responds to visitors’ movements.
