These are several video demonstrations of the Hupfeld Phonoliszt-Violina, a combination of a player piano as well as three violins that are are played using a rotating circular bow and a bunch of robotic fingers to press the strings. Apparently it was all the rage at the World’s Exhibition Of 1910 held in Brussels, Belgium. And I can see why, I’m still amazed and 1910 was like, what, almost ten years ago? “Try a hundred.” WHERE’S MY FLYING CAR?!

Keep going for the videos.
