In the 1950s and '60s Buckminster Fuller (who we wrote about here) envisioned a bright future full of domed cities, spherical houses floating among the clouds, and bliss for all passengers of "spaceship earth." Elizabeth Kolbert writes about his legacy in the latest New Yorker, asking if Fuller "was an important cultural figure because he produced inventions of practical value or because he didn't?" Seeing as how most of us still live on the surface of the earth, in open-top cities, we can guess how that question gets answered. A new slide show of some of Fuller's wackier ideas is here.Via Boing Boing.
