A frozen lake.
A spider's thread when it's climbing downwards.

Aaaaactchhhually a frozen lake would follow the local curvature of the earth, even assuming ideal conditions and crystal formation and so on

I'll going to call you on that one. Surely gravity defines the surface of the lake, not local curvature.

Yeah, that's fair. Still curved though. In my defense I had it right in my brain, the idea got garbled on its way to the keyboard
