Tron theme I'd use EL tape and just commit myself to cutting miles of tiny lines.

Idea I had for a SW repro cab, print cheap plotter template art and mark all the deathstar, engine, and star lights. Drill through for LED hookup on the backside, on art side route in a depression and flush mount tiny plexi discs. (pencil eraser sized). Color code the LED as necessary and hook array to arduino. Pinhole the art before application, apply and program a light show.
If you did the above idea with black and white art and had it printed in a manner similar to what rear window wraps are made of (thousands of tiny holes) then you could use the LEDs to add the color. By filling in the negative space with colored light, at that close range, I'm pretty sure the eye would blend it into a solid sheet of color for you.

Spend several thousand dollars and have custom cut OLED sheets made to fit your cab (already feasible tho asspensive). Hook up to computer as a second monitor and do whatever you want, side art based on game, put two web cams on the top and make it invisible, have it display light shows and give everyone seizures, sky is the limit.
