A few weeks ago I shot some photos in and around the Living Computers: Museum + Labs in Seattle. Check out the classroom/break-out room we can use and the Hooverville Bar where we will have Saturday night dinner.
In the fifth photo down, there is a yellow sofa between two pillars. That sofa will be removed, and the museum have 8-foot tables in a line along those pillars.
Also I made a quick video of the first floor so that PaCommEx attendees can get oriented. See
