I think it's very impressive, as is the maths involved in designing such a structure. To be honest, it's the design aspect of it that interests me the most. I can't really comment on the architectural qualities of it, I'll leave that to Prince Charles. I'm sure he'll be suitably horrified and that's probably worth £19m of anyone's money. But from an engineering point of view that thing is the dog's danglies. I'm not saying it's unique, take a look at some of the rides in places like Alton Towers, but hats off to London for having the guts to go ahead with it. I'd love to see some bigger images of it.
