As far as the carbon freezing chamber is concerned, I think both views are correct. Some of the shapes are definitely walkways, but others may actually be the "web" shape that others are seeing. Some of the art clearly supports the "web" structure, while some of the art and on-set cues indicate walkways.

And I'm a fan of Jaitea's mockup there! That wouldn't be harder than some simple motion tracking.
I have a hard time thinking Ady's not already gone and done this, though. Especially something so noticeable and not hard to fix.
