Are you talking about brushed metal?  That's what those anisotropic shaders everyone
is always talking about do.  I think they require uv coordinates, but a spherical
mapping technically does have those, so it could probably be added to POV-Ray.  But
I digress...

If you can get the spiral correct and increase the frequency below screen res, then
super high AA should create the desired effect.  Just use Adaptive sampling and an
AA depth of like 4 or 5 and a threshold of .01 or something like that.  Then take a
trip somewhere while it renders. ;)
