I was wondering how hard it would be to make it possible to put
upside-down clefs on the right side of the staff. I just wrote a sort
of crab canon that is meant to be read as a treble clef right-side-up,
and a base clef up-side-down (by two different musicians, of course).
I'm not sure how useful this would be in general, but I suppose for some
urtexts it might be handy, since composers used to write some pretty
funky obfuscated canons.
Obviously, if it's very much work, this wouldn't be a worthwhile thing
to do, since pieces meant to be played upside down are definitely in the
minority. :) But if it's easy, it would certainly be cool!
