I wrote previously about the Rem Koolhaas CCTV building in Beijing.  The one they call Big Underpants, the one whose photo should be viewed through cheesecloth for proper effect, given Beijings’ chronic haze.  In fact some days you can barely make him out at all if you are any distance away, and you have to wonder if that’s all of him.

I stayed in the Central Business District a few nights ago.  Sure enough, as I walked out of my hotel in the morning there he was, Big Underpants, emerging from the haze.
