Original version had synchronized music accompaniment
"short abstract animation featuring visual rhythms created by the tempo and movement of circular, triangular, and square objects. Mori’s Senritsu was a black-and-white animation with synchronized music accompaniment, and Shimizu noted how the film attuned the visual images to the rhythm of the music, describing that “this kind of valuable experiment will inspire commercial talkies, more than Mickey Mouse and Silly Symphony do.” - Noriko Morisue, "Filming the Everyday: History, Theory, and Aesthetics of Amateur Cinema in Interwar and Wartime Japan" (Yale University: PhD Dissertation, 2020): 99.
