What is visual programming?

Color Plate 3 at:

shows that physical models can not just inspire but can also be used to
derive and prove things by construction.

I haven't read any other books that use physical models that you could
hold in your hands to derive or prove things.

I think the coordinate system to use for color plate 3 is at:

Are there any examples of proofs with 3D contraptions or physical models
or are all mathematical proofs of theorems paper and pencil proofs? I
found an algorithm to generate permutations with Prograph CPX that I
probably wouldn't have found with a text based computer programming
language. Are there any computer algorithms that have been derived and
proved with physical models that you could hold in your hands, or
computer graphic representations thereof?
