  Using UV mapping with checker pigment on a sphere - no clue at all!

Hi(gh)!

To finally, after 21 years of dabbling with POV-Ray, get my official 
debut scene, I would like to create a checkered sphere - but with UV 
mapping of course.

But when I tried this:

sphere
{
   0, 1
   scale 1000
   texture
   {
     uv_mapping
     pigment
     {
       checker color rgb <0, 0.7, 0.3>, color rgb <0.7, 0, 0.3>
       rotate z*-90
       scale 50
     }
     finish
     {
       ambient 0.05
       diffuse 1
       brilliance 0.3
     }
   }
}

I always get a uniformly colored sphere, regardless how I rotate the 
pattern! Why?

And there is no tutorial around to help me with this - or I'm just too 
stupid to understand them!

See you in Khyberspace!

Yadgar
