The beloved Moleskine notebooks, favorite scrawling pads of Hemingway and Picasso, have gone digital. The company’s new iPad app, The Hand of the Architect, includes 378 drawings by 110 architects, including Michael Graves and Mario Botta (whose sketch of the San Francisco Museum of Art is shown). The works were compiled by the Italian Environment Foundation to raise funds, app proceeds included, to restore architect Piero Portaluppi’s 1935 rationalist Villa Necchi in Milan. Drawings and sketches come accompanied by essays, captions, and biographies of the architects. Even in the age of CAD, some projects still start by hand. • $18.99;
