The family’s coming into town for Thanksgiving, and they’re not going anywhere for the next several days. Before they — or you — go stir crazy, start making a plan to coax them into the minivan (or the Metro) at some point for an art excursion. Even if you can’t talk Uncle Joe off the couch, you might want to consider a solitary ecape of your own from the nonstop football and turkey tetrazzini.

Take a look at a few of our recommendations for special exhibitions, big and small, that you might want to check out over the holiday weekend, here and after the jump.

At the Hirshhorn Museum and Sculpture Garden, a gorgeous installation of 102 silkscreened and painted images from Andy Warhol’s series “Shadows” wraps around the museum’s second floor, stretching 450 linear feet. It’s one of two Warhol shows on current view. Be sure and also see “Warhol: Headlines” at the National Gallery of Art. (Dia Art Foundation. © The Andy Warhol Foundation for the Visual Arts, Inc.

Harry Callahan would have been 100 years old next year. The National Gallery of Art is celebrating the centenary of the pioneering photographer’s birth with the retrospective “Harry Callahan at 100,” which includes the lovely figure study from 1948, “Eleanor, Chicago.” (© Estate of Harry Callahan, courtesy Pace/MacGill Gallery, New York)

Contemporary painter Roger Shimomura’s witty self-portrait “American Pikachu” is part of the exhibition “Portraiture Now: Asian American Portraits of Encounter.” The National Portrait Gallery show, which looks at what it means to be Asian in today’s America, is one of two worthy shows there, the other a compex, prismatic look at the writer Gertrude Stein, “Seeing Gertrude Stein: Five Stories.” (Roger Shimomura/Flomenhaft Gallery New York)

“Unbuilt Washington,” at the National Building Museum, features never-realized design proposals for the capital city — such as this giant TV screen on Pennsylvania Avenue — revealing what D.C. might have looked llke had weirder heads prevailed. Don’t leave the museum without stopping in the gift shop. It’s the best one in town. (Copyright James Allegro and Doug Michels)

“Dis-Member,” a splendid showcase of sculptor David Mordini’s oversize body parts, has been extended through saturday, Nov. 26, at Hillyer Art Space. On closing day, you can meet the artist, who will be in the gallery between noon and 4 p.m. (David Mordini)

Fans of new media will not want to miss “Data/Fields.” The exhibition, which has been extended through Dec. 11 at Artisphere, includes artist Ryoji Ikeda's "data.scan,” a mesmerizing computer installation with sound. (Marissa Long)

Finally, if you need more, not less holiday spirit, you’ll want to visit the U.S. Botanic Garden. Its annual holiday-themed exhibition, “Season’s Greenings,” features a Christmas tree, a working model train and plant-based replicas of Washington landmarks. (U.S. Botanic Garden)
