Simple but unusual bookcases by Faktura Designs

It's hard to make a bookcase interesting, but I'm digging NYC-based Faktura Designs' efforts with their Scala (above), V (below) and Twig (bottom) bookcases.

I'm not totally sold on the 45-degree-angle thing--the book I want will invariably be underneath 20 of its brothers and sisters--but I appreciate their experimental aesthetic, and the way that the edges of the shelves themselves act as bookends in the Scala, my fave of the bunch.
Faktura also makes a variety of tables, you can check 'em out here.
