Chains of derelict boats; reconfigurable floating debris; tightropes; miraculously parted waters; and balloon-zeppelin floating stuff. A lot of agonized political wisecracks that aren't actually ideas for bridges. These were the entries I omitted from my choices because they become instant clichés.
Postcard #152. [top image] I appreciate this deliberate refusal to screech about high technology. This depicts the scene that would evolve if people took less trouble rather than more. It might well be duty-free because there's nobody left with the capacity to organize any duties. A relaxed, earthy "before-and-after-science" scenario where a retired William Shakespeare meets Cervantes on parole.
It would leave a great set of picturesque colossal ruins, too. The "theory of ruin value," as the expansively-minded Albert Speer used to say.
Postcard #6. And, a bonus entry.
