Cauldron

This is another version of the same basic idea, this time with two
pure 9/7 major thirds and some other nice features. I tried to make an
rms version, but didn't like the result (I also rejected what minimax
gave me for grail; this is a delicate business, as Robert suggested.)
However, I do like this one.
