Hyperbola+Machine

My assistant and I want to make this hyperbola generating machine that I remember from a classroom physics laboratory 45 years ago. It is a shallow glass aquarium with water and a vibrating machine (probably on batteries so we didn't kill ourselves) with nails hitting the water generating waves and hyperbolas. Does anyone know any schematics for making this? Below is a GeoGebra simulation. media type="custom" key="8258100"
