No, but the principles are fairly straightforward. I should be able to build something like this with an old speaker, a power supply and a variable resistor of some kind. The surface looks like a frame with a tight cloth over it, much like a canvas picture frame.
Actually rather than build it a blank canvas and a household stereo would do the job.
Some salt or dry crystals would complete the apparatus.
Gah! I don’t have time to make something like this. :) Although it would be fun and it would make a fine addition to my local museum.

Some museums have set ups like this that you can play with. Have you ever been to one?

Funny thing is, most of the images occurring in the latter 2/3 of this video (as stills) look just like “primitive” art…

I showed it to my husband and son - at first my (15 year old) son was saying “that’s boring” but once the video got going he thought it was cool.
