A friend sent me this link, and I haven't found a thread about it here. It's an unconventional filing system based on the premise that filing by name and category is entirely ineffective and the only parameter that matters is how recently a file was used. Tools are one shelf, A4 envelopes, a pen and colored tape. As files are nudged toward the lesser used side of the shelf they are either on tap for being discarded or else ready for "holy" status -- meaning they are important enough to be saved in deep storage.
I'll say this: I HATE file folders and filing cabinets. I do not know why -- it's a visceral thing. So the Noguchi system struck me, if nothing else (yet) as pretty.
