NEED HELP IDENTIFYING A FOREIGN FILM FROM THE FIFTIES, POSSIBLY SIXTIES

MOVIE WAS IN BLACK AND WHITE.  A COUPLE IN THE MOVIE COMES ACROSS A STREET PERFORMER

WHO HAS AN INCREDIBLE KINETIC ART MACHINE, MAYBE EVEN LIKE A RUBE GOLDBERG CONTRAPTION.

I'VE LOOKED EVERYWHERE, INCLUDING BLACK AND WHITE MOVIES BY DECADE, MOVIES THAT DISPLAYED

KINETIC ART, ETC. AND I HAVE BEEN UNABLE TO IDENTIFY THIS OBSCURE FILM.  MUCH APPRECIATED IF

ANYONE HAS ANY INSIGHTS.  IT MAY HAVE BEEN A FRENCH FILM, OR MAYBE AN ITALIAN FILM....I

CAN'T SAY FOR SURE AS THIS WAS YEARS AGO.
