Thr name of the video is based on the book Cymatics by Hans Jenny, who coined the term in the 1960s. The content is more mysticism than science, but interesting. It's a similar sort of thing: making sound visible by using vibrating surfaces.
In addition, there's a lot of very cool animations on this site, representing anything in between baseball bats, musical instruments, and loudspeakers.
Some old stuff, so my apologies if it's already somewhere on the forum.
