Today is the 127th birthday of Sophie Taeuber-Arp (1889–1943). In celebration of this beloved artist, whose face graces Switzerland’s 50 franc bill, Google invited MoMA to create a digital exhibition. We’ve included some beautifully crisp high-resolution images of her art—from one of her Dada Heads to paintings from the 1930s—alongside archival photos and views from recent exhibitions.

Today we honor Dr. Martin Luther King, Jr., and his inspirational legacy. This week’s highlights include a last call to see exhibitions of designs that changed the way we see and hear the world, a members-only bash, and more.

Five for Friday, written by a variety of MoMA staff members, is our attempt to spotlight some of the compelling, charming, and downright curious works in the Museum’s rich collection.

To call David Bowie an art enthusiast would be something of an understatement; at times it seemed that his very existence was an art project.

In 1913 Marcel Duchamp topped a kitchen stool with a bicycle wheel, “fork down” through a hole he had drilled in the seat, and parked this wheel-on-a-stool in his Paris studio. “I didn’t have any special reason to do it,” he later recalled.

Can a dance number change your life? “I Don’t Care,” with wildly imagined choreography by Jack Cole (1911–1974) for Mitzi Gaynor in The I Don’t Care Girl, changed mine. As a dance critic of 30 years, weaned on Balanchine and Cunningham, I’m here to tell you that once you’ve gone Jack, there’s no going back.

When Joaquín Torres-García returned to his native Uruguay in 1934, he was 60 years old and had lived abroad for more than 40 years. During the first years of his American relocation, before he became the referential Master at Taller Torres-García, he founded and directed the Asociación de Arte Constructivo, the achronym for which—AAC—appears signed on most of his paintings from 1935 to 1938. During these years Torres-García created a series of black-and-white abstract paintings that constitute one of the most striking repertoires of synthetic abstraction ever produced in the Americas.

One of the all-time best Christmas presents I ever received was a tiny black plastic transistor radio. It came with a single ear plug, a corded wrist strap, and a thin black vinyl case. There are no words to describe how absolutely fabulous it was, but I have a wonderful memory of bebopping through the snow across the street to my best friend’s house on Christmas night with my new little black transistor radio pressed up close to my ear. I couldn’t wait to show it to her.

Art and film come to life this week with an array of special programs. Check out these highlights:

The New Photography exhibition series—which Quentin Bajac, The Joel and Anne Ehrenkranz Chief Curator of Photography, has called “a window on the Museum’s approach to photography”—has been an influential vehicle for acquisitions for three decades.

Some visitors to MoMA’s Endless House: Intersections of Art and Architecture exhibition tell me Frederick Kiesler’s designs don’t have enough windows. His Endless House couldn’t have connected the inhabitants with their environment, they say, comparing Kiesler’s model to Ludwig Mies van der Rohe’s Farnsworth House, a glass and steel box intended to float among the trees.
