Why not welcome spring with a mobile—or two? Alexander Calder, the originator of the mobile, would certainly approve. As he said, “To most people who look at a mobile, it’s no more than a series of flat objects that move. To a few, though, it may be poetry.” The museum shop carries two cheerful models of mobiles fashioned from colorful, translucent paper attached to silk string. The Circula Mobile ($32) is a single, long garland of paper rings anchored by a magnetic stainless steel weight. The Skektral Mobile ($22), pictured, is made of paper strips rather than rings. Customers are liking the chunky Kaweco ballpoint pen ($62) and mechanical pencil ($70); the brand (tagline: “License to write”) was first introduced in Germany in 1883 and the pens come in a great-looking tin case. The Magno Wooden Radio ($250), designed by Singgih Kartono, has won multiple design awards. The design is simple, beautiful, and eco-friendly. The radios are made by hand by highly skilled craftsmen in Indonesia from carefully chosen wood (the company’s policy is to plant many more trees each year than it uses for its products).
