Dang, I realized that I'd misspelled Giubo (as Guibo) on that other thread, after it was too late to edit. That thread includes background on the doo-hickey, including pronunciation... which I find interesting. It's spoken as joo-bo, named after a guy whose nationality I don't recall (Italian maybe?). I have to remember the spelling and pronunciation by recalling a Hungarian friend named Giulio, spelled in other languages as Julio.
