For me, personally, I think in boxes and lines and when I program, I spend a lot of times scribbling on paper to map relationships between data, to show the data flow between modules or concepts, to show the pipeline stages, that kind of thing. I do it mainly as a way to organise or solidify my thoughts, less to document them. When I used Max/MSP some years ago, I had the interesting experience that I found I didn't need to do this on paper because doing it in Max code was enough. I've wished for a Max-like language more geared towards general purpose programming[1] ever since, but alas, I've yet to find one. [1] Richer data structures (I think it may have got these since actually), tools for unit testing, stuff like that.
