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: http://b2b3.free.fr/confs/ , the first conference and maybe the second generalizing grids to curved shapes. And Yes I was fun too of Hypercard : http://lambdaway.free.fr/lambdawalks/?view=hypercard Today I'm working on a homemade language, lambdatalk, http://lambdaway.free.fr/lambdawalks/ with which I explore lots of algorithms, close to the lowest level, the lambda-calculus, http://lambdaway.free.fr/lambdawalks/i?view=simply Best regards.
