Downstairs in our living room is a display of architectural models--Fallingwater, the Robie House, the Farnsworth House--all courtesy of one precocious 9-year-old and his generous grandparents. Lego has done a beautiful job scaling down these landmarks, and it seems to be adding more to its catalogue all the time.

And who do you suppose designed this cool town hall building set? An architect (click on the little clapperboard symbol at bottom right to watch a video in which she describes her clever and surprisingly intricate model). --b.d.s.
