I was struck by something in this image:
At first glance, you don't see the arch and the ceiling structure, making the room seem more open and expansive. I rather like that effect and I think I'm going to try to do something more with it. I'm not getting rid of the arch but I may try to widen it a little or possibly create openings in the spaces between the girders.
I'm also trying a different configuration for the hub control stations based on some email exchanges that have been going on. Instead of the floating flat screens in a wrap-around arrangement, I'm doing something more like the control stations on the bridge, but I'm keeping the round gauge displays.
More updates later today.
