Yahoo! Picks - bringing you the best of the Web since 1995

This remarkable blog dabbles in "architectural conjecture, urban speculation, (and) landscape futures" above and below Earth's atmosphere. From electromagnetic "Grand Canyons" in space to the traffic galaxies of Los Angeles, there is no place that BLDGBLOG won't explore, or at least survey with some lush, interesting pictures. It plunges into such topics as India's super-highways, tourist photos of Las Vegas, and the Great Man-Made River of Libya. Reading through it, you may find yourself in an occasional state of disbelief: Russia has plans for mining on the moon? In 1960 a man named Joe Kittinger floated 30 kilometers above the Earth -- and then jumped? Which brings us to our final point about Geoff Manaugh, the force behind BLDGBLOG. He clearly has a finely tuned sense of wonder about the world. And for that we're willing to settle in and call BLDGBLOG home.

America witnessed an unparalleled migration to the suburbs in the 1950s, a decade in which 20 million people moved to mass housing developments. One of those communities was Levittown, Pennsylvania, a town that billed itself as "the most perfectly planned community in America." This site, created by the State Museum of Pennsylvania, explores the planning, building, and selling of Levittown. More than just a planned suburb, Levittown sold itself as a community where "everybody lives on the same side of the tracks." This site presents an incredibly detailed look at not only the nuts and bolts of the town but also the psychology of planned communities and those who created them. Have fun exploring this site and learning how Levittown forever altered the American dream.
