For those concerned about the ugly facade, NBBJ tends to design from the inside out; they specialize in complex programs and interior design.
As far as the ugly (I will admit, it's sort of ugly) angled texture, it was experimental. I would've liked to see the vertical lines, but (from an anon source) something about engineering an extremely thin and efficient facade meant making it angled. I didn't get to ask how making lines angled rather than vertical was thinner and more efficient, but then again, I'm no pro in engineering, just an architecture enthusiast.
