A noise is usually a sound that is not elegant enough for being 
considerated in a pretty composition unless it's concrete music, or 
maybe electroacoustic music, from my own point of view.
Playing an image would obviously go into the nodal point of view, in all 
senses of the word.

They both make interesting sounds indeed, but at the end we don't really 
feel the relation between the image and the sound, it's like taking a 
synth a touching all the buttons until a cool sound comes out.

Okay, this is interesting.
 How can we proceed for building a counterpoint from RGB and grey level
