We’re presented with many wonders — objects rendered weightless, or put into permanent vibration, vaporous blue mercury and traffic signals turned into lonely, monstrous eyes. And as the show progresses (it’s surprisingly large, designed to unfold around corners and spring surprises at your back) the work gets less intuitive, and a lot louder. A pendulum, orbiting a strong, floor-mounted magnet, whips eccentrically and not at all gently about its centre of attraction. It’s like nothing in visible nature. There’s no “magnetic breeze” here, no “force like gravity”, just the thing, the weirdness itself. Now we’re getting somewhere.
