I just discovered your project and am totally excited to see your progress! As a fan of the general look of the movie era, I'm happy to see a fan series that is trying to accomplish the same look and feel.
When I was in high school. I built a wedge of the movie bridge (or at least as close as I could do with my limited budget and resources) and understand the scope of this sort of undertaking. Back in the day (around 1987 or so), I didn't have access to large format printers or film, so I hand painted everything on the back of plexiglass and lit it with Christmas Tree lights. The effect on video was amazing and no one ever noticed how wavy some of my elliptical buttons were!
Anyway, here's a glimpse of what my old set looked like. I still have some parts of the panels in my garage, but I doubt that they're anything you can use. I can't wait to see updates!
