The more I've studied that graphic, the more I'm convinced that that's just way too much floor space devote to turbolifts. Especially in the neck! Why??? Answer: it looks suitably tech-y for the one shot it's in.
Actually it seems like I read once somewhere that Rick Sternbach had something to do with this particular graphic and that it was kind of a rough, none-to-well thought out display. Although, I could have that totally wrong.... You out there Rick?
