It seems to me that we would've posted this before, though I can't seem to find any record of it. And if we have, I think it's well worth another entry. It's such a great design and so terribly great-looking as to inspire need (as in, I need that piece of furniture). And, of course, it's by Ronan & Erwan Bouroullec for Cappellini (2004). "the cloud shelving system...has garnered much attention due to its original form and its use of innovative materials. cloud allows for the repetition of elements which can be stacked and aligned to create large bookshelves or room dividers. in theory, there is no limit to the size of a structure other than the size of the space containing it. cloud is made of a high-density polystyrene and is available in 4 colors: white, light green, dark green or red." units sold separately. 73.8" x 15.75" x 41.4"
