I came across this - the "Headstand Hornpipe" ( authorship attributed, I believe, to Frederick Link ).   It was a photo-copy of a page from a clarinet tuition book - 

OK - so - of course - I could not resist - a piece in two-part harmony where part 2 is simply the score backwards....  uh-huh....  cool... so - doing what I do - I transcribed it as two parts into MuseScore.   I initially set the voice to violin - but - know what - without doing a lot of messing with it - it wasn't that great sounding...  so I went for the clarinet voice - quite pleasing - here's the two-part score - it might be very nice on viola actually - maybe in G - whatever - 

  And - here - somewhere below - is what it sounds like when played by machine - I quite like it and I might ( if I can force myself away from practicing rolls on fiddle ) re-score it and have a shot on viola - mixing both parts - we'll see )...
