The motors I build there were exactly as I imagined them. I made no attempt to improve the design, but merely reproduced the pictures as they appeared to my vision and the operation was always as I expected.
Flow systems have two basic features (properties). There is the current that is flowing (for example, fluid, heat, mass, or information) and the design through which it flows.
The flip side of the coin was that even good programmers and language designers tended to do terrible extensions when they were in the heat of programming, because design is something that is best done slowly and carefully.
Whether it's the experiments on 'MythBusters' or my earlier work in special effects for movies, I've regularly had to do things that were never done before, from designing complex motion-control rigs to figuring out how to animate chocolate.
Lines slip easily down the accustomed grooves. The old designs are copied so glibly that we are half inclined to think them original, save for that very glibness.
