Do Ho Suh's exhibition at MMCA Seoul has become a phenomenon: weekly booking slots sell out as soon as they are released, and long lines form outside the museum as visitors hope to enter on the spot, including through canceled reservations. To keep viewing conditions comfortable, the museum caps daily attendance at 6,000. The appeal lies in works that make the nameless collective the protagonist. 'Who Am We?' (2000), on view in Gallery 5, appears at first as blank wallpaper until viewers draw close enough for hundreds of tiny yearbook faces to emerge. Elsewhere, tens of thousands of miniature human figures hold up a glass floor, suggesting that unseen multitudes sustain society. 'Nest/s,' a 22-meter corridor work, stitches together the hallways and doors of Suh's former homes in Seoul, New York, Berlin and London in translucent fabric. The show runs 164 days through February 9. If the current pace holds, cumulative attendance is projected to approach 800,000, which would set a record for a single exhibition at MMCA Seoul — surpassing the Choe U-Ram show's 650,000. Museum shop merchandise incorporating the artist's work, including T-shirts, keeps selling out.
