Model Building

Architectural models in Lego? Hmmmm. Arcosanti 5000 could be built in a week for a few hundred bucks.

Seriously, though. This could be a quick and dirty way for an architect or builder to make a scale, 3D model of even small projects like a house remodeling. That way, those who have problems visualizing something from a blue print will be able to figure out that the stairs don't only go down....
