No, no I cannot. In a way I can make the whole structure sag, but the
segments would still be straight. See, the macro only looks at two lines
at a time. There is no real network in place, where point associations
between many lines are kept. I thought about using some kind of pointer
system, where elements are pointed at by other elements, but I haven't
found a good way to do this. Some mesh techniques involving things like
Delaunay triangulation would be the next real step, but I'm way out of
my league there.
I suppose I could give some segments a curved, sagging appearance, but
to maintain the illusion of tautness, it would have to be done very
carefully.

You forgot the bird... Then the cat, then the dog, then the goat, then the cow, then
the horse...

LOL. I didn't know that one!

Excellent, ingenious idea. Makes my nose tickle just looking at it. I don't
think I've ever seen proper dust attempted like this in any cg - the medium
usually tends to pristine clean-room perfection!
Could be a bit of mileage in leaving imprints, writing your name, etc :)

Very cool! We have lots of black widow spiders in our area and their webs look
like this. The dust looks great, too. Ingenious in every detail.

Around here, it stops at the cat. We like to let him think he's the top
of the food chain (though the infrequent visits from bears and coyotes
sort of ruin that notion).

I don't know about that. A real wizard wears a funny hat (oddly
resembling a dunce cap), and knows the ways of Voronoi, whereas I only
know the basic concepts and failed high school alchemy.

"Clean me" is always a classic message ;) Doing something like that
shouldn't be too hard. It would require wrapping the AOI and slope
patterns into an image-based pattern (or vice-versus), and also using
the same image as a condition under which objects can be placed with
trace().

Yeah, they sort of do resemble the tough, springy webs spun from black
widows. That's one spider we don't tolerate. Well, except for the time I
allowed one to live in the garden. Come watering time, she would always
exit her dwelling for a drink :)
