So much awesome...

I've had a question about snow machine, maybe I asked before but I don't remember the answer...  Does it need actual geometry to work properly, or will it also produce snow accurately on displaced details?

I've long tried to figure how to model power and phone lines in urban environments.  One of the things I tried was just drawing slight curves on planes and using those instead of actual geometry.  If the lines were displaced slightly, would snow "collect" on them?
