   Tek, this is just great. I'm writing a "ceramic tile generator" 
macro, and my method to mirror the pattern really sucked... your method 
is much more elegant and useful, and produces much nicer results:

   These are a few of the endless posibilities. The macro consists on 
some trig functions used as pigments with carefully-crafted color maps, 
and using your "rotated warps" effect for the repetition around z.

   Many thanks for sharing such discovery: it was a beautiful new year 
present!
