I was able to enter a working session this morning and take a few photos.  The working sessions are closed to the press, but are webcast.  (No, I didn't sneak in.  This was an official, organized, approved photo opportunity, because the sessions are not as crowded today as they have been.)

This was the Accelerating Green Building session of the Energy and Climate Change track.  The first gives a sense of the room.



The second better shows how the panel is situated.



I am using a wide-angle snapshot camera and the room is smaller than these pictures imply.  In fact the second picture more accurately represents what it is like to be at almost any table in the room, feeling like the panelists are right there with you. 

There is a much closer sense of intimacy in this room than in the plenary sessions.  This is intentional, and fosters creative discussion.  The panel talks, there are questions, and then the participants discuss the topic at the tables, in a brainstorming process, coming up with ideas for solving problems.  These are the ideas that some of the attendees might decide to take on as commitments.
