If you're going to Washington D.C. before September 3, you can't miss the Lego Architecture exhibition at the National Building Museum. They just added three new iconic buildings to the 15 already in existence. They are huge!
These three new models took a combined 641 hours to create. The entire exhibit includes the Chicago Spire, the Burj Khalifa, my beloved Frank Lloyd Wright Fallingwater, the John Hancock Center and the Empire State Building, all with amazing detail and scale. [NBM]
