At the Mirror is an exhibition of 20th century Japanese woodblock prints in the Martin and McCormick gallery at the Denver Art Museum. Designed by Daniel Libeskind, the gallery is enclosed by a sloped ceiling and a combination of sloped and vertical walls. The exhibition cuts through the gallery’s irregular volume in two directions. Five fin walls divide the interior into narrow, vertical slots that position visitors close to the show’s intricate prints, which are traditionally viewed in houses and apartments. A floating white stripe splits the gallery horizontally. The room’s oblique walls, which usually define the space, disappear except where they register as inflections in the stripe.
