It’s called Cymatics. A fun gadget to demonstrate standing waves and to drive everybody crazy with in the shop. It’s a speaker enclosure with a thin membrane, topped with some gross powdered drink mix because it was the only convenient powder we had that wasn’t hazardous. This was a prototype for a client job, intended to demonstrate that a 30 foot one of these would be so outrageously annoying that it would be rendered impractical.  Ernst Chladni had his plates, I have my Saran Wrap.
