Lene Rønsholt Wille, a Denmark-based designer, made this Great Wall of Lego. It took her six weeks to build, using 270,000 pieces!
She actually calls the wall ‘Metaphorical Horizons’ and says it can be used as a bench, desk, wall and space. It’s located in the central hall of the World Trade centre in Amsterdam.More details and pics here: Metaphorical Horizons, 75 photos
