From the fun that is WorldChanging, check out "The Rocketship Wonder of Earlier Decades is Gone." My favorite bit is the description of an architecture firm as "one of the world’s most valuable imaginative resources: technically accomplished, with a healthy streak of insanity. He would be the guy the evil genius would go to for the Volcano base plans. 'Ten billion in blood money, what can you build me?' 'A death-maze constructed from recycled local materials and plutonium!' Something like that."
