Are you seated comfortably? Probably not, if you’re reading this at work. Sitting at a desk all day can kill, according to the title of Barbara Visser and RAAAF’s short film, or at least give you problems that not even exercise (or occasionally rising to your feet) can cure. They’ve taken a stand on behalf of desk-bound workers across the world with the star of their animation, the Outstanding Landscape of Affordances. This mammoth structure does more than alter the topography of today’s workplace; it fills the office with a gigantic labyrinthine mountain. Half office interior, half obstacle course, the project at the heart of Sitting Kills aims to increase the mental and physical activity of all who squirm and shift to find the optimal working position.
