Feature request: knots "mesh gray style"

[pablgonz]

Hi, looking for a package for something else I came across this nice figure.

which is part of the documentation for the fiziko package that uses metapost for drawings.

You could get such an output in spath3?

I think it would be a nice feature.
Regards

That's ... quite something! I'm not even sure where to begin with that.

@loopspace Thanks for taking the time to look at this, I really wanted to propose some code for this, but failed miserably, I rummaged through several forums for some tikz style but nothing....I think today it is more common to see everything in color than the old school black and white style (which I like a lot).
