The whole discussion reminds of perhaps the only remotely useful 
postcript program I have written, to draw the parts of an Astrolabe. I 
really ought to finish that project in fact, so far I have done it on 
paper and cardboard, but I'd really like to build one in plywood...

Even had fun putting in transformations that leave a very funny looking, 
but still theoretically working astrolabe, as attached :-) (this is just 
  one of the most visible parts, of course).

Thing is, I'm not sure I'd understand how that program works, 3 years 
later :-D

Anyway, is that kind of thing called a nomogram as well?
