Now here's something a little different: a display shelf, with picture frames hanging from the bottom of it. We like framed wall art, and we like collections on shelves — we even like framed art leaning on shelves. Here's a way to get it all if wall space is really at a premium. The pictures slide along the bottom of the shelf independently of one another on metal tracks, while the shelf itself is made of Indonesian mahogany, which they swear is sustainable. $98, here.
