    Oh, I knew that; sorry if my posting was confusing.

    Thank you!

    Yes, they are.  I used an exponent of 2 for one of the arguments, driving

expect.  It will still have the rounded edges, but the corners will be square.
I just slice the top off, scale and rotate, and use that as my tile.
    For the mildew, I used a bozo pattern and put a couple of narrow color_map
entries in it to make the appearance of the troublesome growth.  That was
applied to the grout.  The water droplets are blobs with ior=1.4, but I am not
satisfied with the results.  I will probably redo this with photons, just to see
how it will look.

Cheers!
