Feedback / Squelch - Acoustic / Optical/Reflective / Photonic-2 / Electric / Internet

Purely Acoustic Feedback / Squelch
Can Acoustic Feedback / Squelch be achieved purely acoustically, that is, without any type of electric device, and if so, any interesting effects.
  Of course I assume most non-electric music instruments may do this.

Purely Optical/Reflective Feedback / Squelch
Can Optical/Reflective Feedback / Squelch be achieved purely Optically/Reflectively, without any type of electric device, and if so, any interesting effects.
   EXAMPLE 1 - A mirror facing another mirror, and the endless? size diminishing corridor of those reflections.   In that scenario, for some reason, I suspect that since that effect could never be performed totally / 100-percent free from vibration, that it really puts the speed of light to the test / limit, and that that factor can limit the amount of of repeated reflections produced ( apart from other factors like the microscopic grain texture on the mirrors surface and maybe other factors ).  Also, when I try this simple test, I maybe detect some type of instability occurring ( assuming it is not just the unavoidable vibration, something else ? )
   EXAMPLE 2 - A laser is aimed straight at a mirror and somehow the laser is replaced with another mirror so that the laser will bounce between the 2 mirrors for whatever amount of time, this could 'maybe' be possible by using a very long distance and by having a flat? mirror-cover that can move ( or rotate ? ) in front of the laser.
   EXAMPLE 2 - A version or versions of the above using some advanced quality of optical-fiber.
   EXAMPLE 3 - I have read in the past about at least one experiment to keep light in a box made of electromagnetic-mirrors, so it was probably a special frequency of light, maybe this setup could be used to try and make some sort of  squelch using light in that box.
   NOTE - They have been able to to make one laser deflect/bounce off another laser, but that does not seem like a squelch.

Photonic-Electric Feedback / Squelch
For example, you have an ultra high quality version of something like a small solar-panel / photoelectric-cell?, and you loop the output of the panel / cell to some type of light-emitter ( SOMETHING LIKE A FLASHLIGHT OR LASER-BEAM ) and simply aim that light-emitter straight back at the  panel / cell.  Also, it would be useful if the light-emitter is in a half-sphere reflector like common flashlights, and maybe it would also be useful if the small solar-panel / photoelectric-cell?, is also in a half-sphere reflector.
     Could this produce any interesting effects.

Electric Feedback / Squelch
This one is obviously common and used for radio-receivers etc., is there overunity here, or, any interesting effects.

Internet Feedback / Squelch
   EXAMPLE 1 - You have a high-res webcam aimed straight at your screen, and you put this live-feed onto the internet on some webpage, and then go to that webpage to display it on your screen, could this produce any interesting effects ( other than the repeated mirror images ), could it under any circumstances affect a link / portion of the internet.
   EXAMPLE 2 - You have a microphone connected to your computer, and something emitting a constant sound which is not connected to your computer, and you put this live-feed audio onto the internet on some webpage, and then go to that webpage to display it on your web-browser, and obviously to hear it, and then aim your microphone at the loudspeakers of your computer and switch of the external device emitting the constant sound which is not connected to your computer, could this produce any interesting effects, could it under any circumstances affect a link / portion of the internet.
   EXAMPLE 2  - Pretending there is a virtual/emulated/simulated web-browser ( that can actually browse the internet ) available on the internet that is on a webpage so that you can go to it on your installed web-browser, and then, on that virtual/emulated/simulated web-browser, you go to either -
           ( 1 ) - You go to a live-feed full-size video of your actual desktop which you have put on the internet somewhere, and of course on your installed web-browser on that live-feed is the virtual/emulated/simulated web-browser that is on a webpage, and that virtual/emulated/simulated web-browser shows the live-feed full-size video of your actual desktop which you have put on the internet.   Could this produce any interesting effects, could it under any circumstances affect a link / portion of the internet.
            ( 2 ) - Or, You go again to the virtual/emulated/simulated web-browser and keep repeating that, so for this particular one, I don't think I can see much interesting effects.
   EXAMPLE 3  - You have a server at home on which you have a virtual/emulated/simulated web-browser ( that can actually browse the internet ) that is on a webpage, ( the difference in this one being that this virtual-browser only shows what you are browsing at home ), and on your server machine at home you go to it, I'm not sure if I got all the details correct on this one.
