Static distortion in Jitter?

Hi,
I am working on a project where I am interested in having an image/video distorted by the static sound of a detuned radio.
Originally I had the idea of trying to create a spectrogram of the signal and the spectrogram would reveal the image which would be somehow superimposed onto it. I then became inspired by Semiconductors work on the piece 20Hz http://www.youtube.com/watch?v=65bsKTI8SdA
I want to try and create areas of movement in stationary pictures, I'm especially interested in wavy lines distorting/bulging the image - I can best imagine this as some sort of oscillating function which introduces lines over part of the image. I have tried to make a patch which does something similar to what I have described and it does sort of work.

I'm stuck at this point, and really want to take the idea further. Any links, example patches or other examples of artists working with similar techniques would be really appreciated.

Cheers
