     There was a scene I did once where I wanted gold plated like
cross hatched floor tiles.
    What I ended up doing was to create the pattern I wanted using
pov primitives. I set the camera so it was viewed at center with only
ambient lighting.
    I then rendered the scene and used that for a tiled  image map and
a bump map for the real floor. If you don't use the once option it will
repeat continuosly. Just make sure you rotate the image map the right
direction.
    For the bump map I made a copy of the image map and converted
it to greyscale. It looked pretty realist once done.

    You could also try making a repeating pattern and render it using the
hf_gray
setting then use it for a tiled height_field. Maybe a brick pigment using white
and gray. Then use a regular brick pigment/texture on it afterward.
Just a thought anyway.

That bricks pattern seen on povray.binaries.images looks pretty interesting
and the source was just posted for that today. I didn't look to see how it
was done though.
