In 1935, architect Frank Lloyd Wright designed Fallingwater, a house atop a waterfall in Pennsylvania. It's a beautiful house, and I've visited it several times to wander around and think, "Yeah, this is what I'd like if I had a gajillion dollars."
Here's one way to experience it from home—a 3D-rendered fly-through showing how the structure is put together. In this video, animator Cristóbal Vila shows us how Fallingwater emerges from the landscape and builds up, plus how cantilevering allows the house to rest on a very unusual foundation. Have a look (and skip to 0:40 if you don't care for opening credits):
For more on the house and its history, here's a half-hour documentary:
Finally, if you're a Fallingwater fan who likes to build things, I recommend the LEGO Fallingwater kit.
