Visitors to UCCA Center for Contemporary Art‘s “Carsten Höller: Two” do not choose which version of the exhibition they enter — a random assignment at the door decides it for them, with no way back to the other side.On view at UCCA Beijing through January 31, 2027, a leading Chinese institution connecting local and international contemporary art, the Great Hall splits into two parallel environments, one rendered in color and one in black-and-white, staging the same works under different conditions. What Höller calls a “Laboratory of Doubt” turns out, in practice, to be a show that removes the viewer’s control over their own experience before it even begins.
Doubling as method runs through the exhibition’s opening gesture, the two-channel video Twins (Tokyo, New York, Paris, Santiago, Vienna, Belgium, London, Milan, Santander, Beijing) (2005–2018), in which pairs of identical twins recorded across ten cities deliver contradictory statements to camera. Resemblance, rather than clarifying anything, produces a riddle with no resolution — an instability that carries into Sliding Doors Square (2026), a corridor of mirrored automatic doors where a visitor’s own reflection can be broken at any moment by someone entering from the opposite direction, part of the same parallel color and black-and-white staging that defines “Two” as a whole.
Time becomes unstable in Pill Clock (2026), a mechanism that drops a capsule containing what UCCA calls an “undisclosed substance” onto the floor every three seconds — roughly, UCCA says, the interval the human mind perceives as “the present.” The capsules, which visitors are permitted to swallow, accumulate into a mound that grows across the show’s run, turning duration into physical accumulation rather than abstraction. The Pill Clock installation sits alongside Sexagesimal Clock (2026) and Decimal Clock (Salmon Rose and Novial Gold) (2021), positioned on opposite sides of the Great Hall to translate standard timekeeping into competing systems — one built from accumulating neon rings, the other drawn from the decimal time briefly adopted during the French Revolution.
Play resists ease in the Tilted Carousel sculpture pairing — Five Colours and Two Whites, both made specifically for this show and rotating in opposite directions on either side of the hall — which turns at a pace too slow to read as entertainment, holding riders in place for a full revolution before releasing them. The device extends one Höller has returned to before, including his Pink Mirror Carousel, installed on the ice rink of the Kulm Hotel in St Moritz.
Chance and reward govern several of the show’s other systems, staged across the UCCA Open Gallery. Dice (Chinese Marble) (2026) enlarges a familiar object of luck into a climbable marble structure with a hollow chamber at its core, while Beijing Dots (2026) uses tracked spotlights to “reward” or “punish” visitor interactions by shifting the colors assigned to each participant. Sluice (2026, with Valia Fetisov) turns chance involuntary: two sets of transparent sliding doors appear to offer a shortcut through the exhibition, but the second pair will not open until visitors — through information passed from others or trial and error — stand motionless for thirty seconds.
Sleep and its aftermath become material in Two Roaming Beds (Grey) (2015), a pair of robotic beds that drift at random through the exhibition space overnight, tracing the visitor’s unconscious movement onto the floor as a drawing they discover only on waking. The overnight stay is paired with Insensatus, a toothpaste developed specifically for the exhibition.
Perception is manipulated more directly in the immersive light and sound installation Light Wall (2000/2026) and Light Wall (Red and Blue) (2026), where flashing light and stereo sound are tuned toward synchronizing visitors’ brain waves, occasionally producing hallucinated color even from all-white bulbs. Spinning Amanita (Black and White) (2026), a monochrome mushroom replica turning at high speed, plays a related trick on the eye; its painted counterpart, Spinning Amanita (Coloured) (2025), rotates at the same velocity in the exhibition’s color half.
Division and inheritance surface in a slower register elsewhere in Höller’s practice. The Divisions series (2018–2026) bisects canvases through repeated procedural rules, generating compositions that approach infinity without resolving into it. Smell of My Mother and Smell of My Father (both 2017) disperse reconstructed scent molecules beneath a bench, letting visitors briefly carry the artist’s own lineage on their skin.
A quieter closing gesture sits toward the end of the show. Giant Triple Mushroom (2024) fuses enlarged cross-sections of three mushroom species into a single sculptural form — not a resolution of their differences, but a record of how distinct shapes can emerge from the same origin, left standing in the Great Hall for visitors to pass on their way out.
