Uh... actually, no. Besides the fact that the proper ASCII rendition
would be "Pluecker", I think the only thing I truly know about that
coordinate system is that I have not the faintest idea what it even does :)

(Well, from the Wikipedia page I do grasp that it uses /some/ set of six
values to identify straight lines, rather than using a set of three
values to identify points. But that's about as far as I get without
having to cool my brain with liquid nitrogen.)
