What the hell?

Good Friday bras!
Today I wanna talk you about a really weird instrument.
I'm referring to Circular Harp; yea, you're readin' right. I found an article on Odd Music website, but I can't find any video or song which could show me how it fucking sounds.
I post whole the article below, but the questions are: have you ever heard about this? How it sounds? Can you link me something which could enlighten me about this?
It made me mad D:

Anyway, enjoy this article:

Circular Harp


Created by David Murphy, the giant circular harp is an acoustic instrument, which looks a bit like a very large kettledrum. It contains 66 strings, strung in a complex pattern across the top.
During performance, which usually requires three people, a video camera points down at the instrument from above, and vibrations from plucked and hammered strings are fed into bowls of liquid.




This makes patterns which are projected onto a large screen, as the sound is fed into small speakers underneath in which containers of water or mercury have cameras trained on them.
The resulting images are then superimposed to make interesting visual effects.
