These shelves are awesome, I love when the shelves disappear against the walls and only the color of the stuff ON the shelves is what really catches your eye. Seems to me its less "great shelves" and more "great stuff!"
Love how these bookshelves pull double duty. Not too sure how these would fare in earthquake country..... Could be a great way to divide up workspaces for various people in a large shared room such as a loft. Maybe with alternating backs?
