I’ve always thought it would be cool to have a printed out minimum spanning tree starting from my house (or work) with miles marked out on it. You wouldn’t need OSM or google maps then!
This reminded me of something similar: https://gajitz.com/scrolling-down-the-highway-vintage-1927-a... It's a watch-like, wrist device called the "Plus Four Wristlet Route Indicator", and it dates back to 1927.
When I was a little kid I wanted a computer so bad that I was even thinking to build a box with some sort of changing "screen" that'd be a roll of paper with some images attached to it. Turns out I wasn't that crazy.
Ha, I did the same. Built little casings in LEGOs. Good times
