While we do like the simplicity and sleekness of the lamp, what we actually wanted to point out was how great the basic Billy bookcases look when they’re in multiples. Since they’re the Billy with optional height extension units, they could look just like built-ins in the right space. (And note the different-sized shelves. They look much better than having everything lined up in perfect little rows.)
Since this is SF, however, we suggest bolting them to the wall so they don’t fall over during a quake.
