Cut and paste error. And too much time has expired and now I can't edit the post to fix it.

Actually, right now the room is set up with the 6' tall, 50cm deep shelves on the south wall and the 30cm deep 8' tall shelves on the north wall. When we got the projector and ceiling mount, I discovered the error of my ways. Routing the cabling up the south wall, over the bevel and across the ceiling to the projector was going to be a major hassle because the south wall is an exterior wall that's full of insulation. The set-up as drawn is the planned set-up which includes swapping the bookshelves north to south. A Big Job! But then we can mount the projector on the ceiling instead of having it up on a 4' stand behind the couch. The person sitting in the middle position on the couch has to slouch right now

Take Care!
