Lumped together under the name "Traveler," in an allusion to both space and time, are two separate installations by Cai Guo-Qiang open Saturday at the Hirshhorn Museum and Sculpture Garden and the Arthur M. Sackler Gallery. At the Hirshhorn, the Chinese artist's gunpowder drawings -- sketches for a planned series of large-scale explosions -- go on view, while the Sackler features the weathered hull of a Japanese boat resting on a porcelain sea. Call 202-633-1000.
