I am an interior design student and I'm working on a project. I remember seeing a bookshelf, I can't remember where I saw it (either surrounded by a design mag or on the web). I want to use it in my project, but I can't find it!
It be several bookshelves, on a pulley system on a wall, it's a little complex to explain. One accesses paperwork by separating the bookshelves, they just fly along. The shelves themselves are at right angles to the wall, encased between the veritcal bookshelves.
The picture I saw had washed out, grey, blue, black & white shelves. I am not sure on the material.
I conjecture it was call "Barcode" or "Bar code", however I can't find it with turn upside down engines. Does anyone know of this bookshelf? what site can I find it on?

Thanks
