ok visited the link and read a little more about it.
The sliding top is eh, i see no point in paying homage to "a hole in the roof" when it's an inferior design to a totally retractable roof, but whatever.
Next I like te two sliding doors at the ends, It will be interesting to see how they implement filtering of people though. It's a little odd to have this oval building cut by such a drastic line of symmetry, but oh well.
Last but not least, I don't get how it will "glow blue" unless they are planning on installying lights to glow out of the window, in which chase like I said ETFE foil is a much more green, economical, and cool material to use (they could change the ENITRE stadiums color if they used it).
Still has some nice features.
