You just have to love the Chinese. They are master designers with a flair for the dramatic & the National Swim Center bubble they have designed is pure aesthetically-pleasing poetry. What do we have in North America that compares? Nothing, nada, zip, zilch. Why? I'm not sure, but maybe it's the chemical soup we live in over here or the extreme excess we indulge in that makes extremely deep thoughts die before they reach our brain stems. Either way, the Chinese have been out-building, out-thinking, & out-smarting North America for centuries and they've done most of it on a diet of Ichiban Noodles with no known nutritional value whatsoever.
