Making and looking at curves can make one happy. Wondering endlessly about this bookshelf and its curves’ ability to support books is not unlike viewing a Cindy Sherman photograph, then pondering how it is at all possible. And that’s only the magical part. Here, extrusion technology goes out on a date with impressionism, producing a whimsical wall offspring, as well as a shrine for your books. Organic and meditative, Ron Arad’s Bookworm bookshelf can easily be made to resemble the peaceful sea coils of “Les Betes de la Mer,” among others.
