"Cribs" for spiders

Isn't that what the cool people call houses these days, "cribs"? This is a spider's crib!
They are these lovely, floaty, thin, crescent moon shaped, webs.

Here, it's a regular neighborhood... ( "web crib" in the hood... hee hee)
During the day, they disappear, but in the mornings they are all over the field. I think that many movie producer's get their ideas from nature. These are something I could see in a movie like "Avitar". Or maybe someday I'll see them in a children's book as some part of the illustration.
Cool, yes?
