I like it, but I think it would freak out some arachnophobic tourists if used on a showcave!
I once 'lost' two tourists off a trip down Robin Hood's Cave at Creswell Crags, after I'd warned the group, at the entrance, about the large number of cave spiders. One half of the couple freaked out, describing what I'd said as a 'hideous image', and they legged it. To be fair I had been telling the story about watching an egg sac hatch over someone's head; don't know why they were worrying, they had a helmet on! I was a bit more wary of telling that story afterwards...
I can't imagine their sensitive sort wanting to wander through a giant web into a mysterious underworld,. but it is quite pretty nonetheless.
