after reading this thread, I attempted to make a replica of the Sydney Harbour Bridge.
Its the bridge that had the fire works all over it in the opening of the Sydney 2000 Olympics.
I had all the greatest of intentions, I carefully sculpted the landscape, I then spent ages building its complex design (working from photos).
The resulting bridge fell to the seabed like a sack of spuds! I lightened it up a bit and re-inforced it but it still broke 60 links and only JUST supported a single carriage.
I won't bother posting it, however, if anyone else wants to take a shot at this one, feel free...
