analog noise is also related to the microwave background radiation of the 

there are ways to use the feedback for other sorts of disturbances; I used 
broadcast equipment I procured years ago from Film-Video Arts (3/4" stuff) 
to create 'trance' videos; with high magnification, images began to appear 
or so it seemed; these were videos on the edge of collapse, had to use a 
wave-form monitor to ensure they would run at all. looking into the videos 
puts one into a trance, not based on the 7hz or other low-freqency 
patterns -

I did a similar thing with a photocopier that was malfunctioning and an a4 picture of Kathy Acker from Blitz magazine (circa 1985?) : Scanned in a copy that came out poor quality and sepia, then put that through again, ripped the copy of the copy, then layered that over the first and scanned, ripped, scanned, ad infinitum.

The dystopian reality of nature always finds a way to carry on mutating the world to ensure survival, even against the elements that seem most capable of resisting that mutation (corporate electronics/apple etc).
