To this day, I’ve never seen the movie, but I did read the book, and based on my parents’ description of the movie, it sounds like a lot of stuff will go right over your head unless you read it. That’s a hazard of trying to compress an extremely detailed story into movie format; I saw the same thing with The Godfather, where some scenes didn’t make any sense to me until I read the book.
That could be a Raspberry Pi project. Most of the hardware work would be the faceplate (at least for a one-off). It might be doable with 3D printing, or laser cutting if you preferred metal.
