Well, it’s not exactly natural, but when I walked by this construction site, the yellow netting caught my eye.

The shape of the netting definitely put me in mind of a paraboloid.

But maybe I’m just looking too hard.

Shouldn’t it be some kind of catenary…oid?

Shhhh…..

Well, fine, if you are going to spoil it, the least you can do is generate an appropriate image / equation.
