This effect reminds me of Ben Franklin's glass harmonica or whatever he called it. It was based on rubbing tuned glass disks with his fingertips to play tunes. I wonder if a series of vocal tones from rotating glass plates would contain spirit voices too.
One plate could be turned by a record player turntable while the sponge is held against it. Maybe a few layers of wool could support the plate without dampening the vibs.
