Just returned from a two week business trip that, for the first time, got me around the world in a single trip: Chicago, Tokyo, Seoul, Daejon, Singapore, London, Berlin, London, and back to Chicago. It was a tight schedule during the local work days plus a second work day at night doing email and conference calls with the US. But I got out a little and here is some of what I saw ...
This is the Deutsche Bahn (DB) head quarters right next to the Sony Center in Berlin. I really enjoy the non-rectangular architecture of glass and steel buildings they erected in the late 1990s. What was amazing is that they'd allow individual windows to open in an otherwise air conditioned building.
