Ya, I got it for my birthday from my uncle and his family, and they got the Falling Water set for a clearance price. This is a good thing considering LEGO rips the forget out of everyone selling it usually for over $100.
Anyways, I just finished, and I wanted to show everyone the set, not the one I just built.
Falling Water is the most famous, non-royalty, non-government house in the whole world. Frank Lloyd Wright, arguably one of the greatest architects in the world, designed it in 1935.

It's concept was to be a very natural house, located on the site of a waterfall. It was to be the home of the Kaufmanns.

The actual house is a historic landmark, which is the only Wright house with the furniture still intact.
In my opinion, Falling Water is a loving awesome house.
