Our favorite sketchbook has gone digital! Moleskine presents The Hand of the Architect – an iPad app featuring 378 sketches and drawings from 110 internationally renowned architects, such as Assadi, Botta, Fuksas, Graves, Gregotti, Hadid, Foster and Piano, “showing that every project always begins by hand”. All the works were collected by FAI (Italian National Trust) with the aim of raising funds to restore Piero Portaluppi’s Villa Necchi, known as a 1930s masterpiece of Italian rationalism in Milan. Sketches and drawings are accompanied by essays, captions and the biographies of the architects. You can purchase the app for $18.99 here on iTunes.
