Thanks chaps! Always nice to be appreciated for the marbles one has misplaced - I'll try not to let you down!
I admit, this has become an obsession - I hate to say I'm going to do something and then not do it. And once I have an idea, it won't leave me alone until it is done.
Interestingly, Bezzo, along with the Crystal Palace, a number of Victorian piers were a part of the early inspiration for this project. I also looked at the iron work at St. Pancras station, along with Leeds, York, and other Victorian stations built under cover. (Unfortunately, the station at my home town of Sheffield is not so grand - we produced all the iron and steel, but every other bugger benefitted!)
The development of iron work engineering by men like IKB and Paxton allowed for massive single-span roofs which give those places a cathedral-like quality which I always found awe-inspiring as a boy. I remember them fondly.
The original idea for this massive rivet-festooned project was that I was going to build a Victorian moon base, set upon legs like those at Brighton pier, and with barrel-vault roofs along all the passageways and bio-domes. Somehow, my sketches inspired me to turn the whole thing into a vehice instead.
I may still do the moon base one day, when I have a few hundred thousand rivets and five years to spare.
On the other hand, if anyone else feels like having a go, you'd better get started...
