Stan’s earlier post on Flexitube really reminded me of Ron Arad’s RTW (Reinventing The Wheel) shelving cum divider unit which he designed 10 years back. Famous for his Bookworm shelving and FPE chair, the UK-based architect/ interior/ industrial designer designed this ingenious piece of storage system in such a way that when you push it, a hub-less wheel-inside-a-wheel design keeps your books and CDs level as it turns. This means that you can basically roll the whole thing across the room and not have to move a single thing on it. Clever? Yes, it is.
