Very interesting, thank you for sharing.
As an architect I used grids to help me drawing everythings, a mix of feets and inches, close to the MODULOR "invented" by Le Corbusier, a french architect. You could see here:

And Yes I was fun too of Hypercard :

Today I'm working on a homemade language, lambdatalk,
