Someday maybe I’ll write another (or my first?) thoughtful post, full of original ideas explicated at length. But for now… more bookshelves! Presenting… the Elastico, by Arianna Vivenzio. Not suitable for the OED, but a shelf’s worth of Aubrey/Maturin novels would probably look swell.
Sadly, this appears to be a design study (go here and click on ‘projects,’ then ‘furniture’), and not for sale. Though you could probably make your own out of a truck’s fan belt.
Many thanks to Nancy for the link.
