the way i've done this (in flash, of all things) is to create a nice bitmap of ... noise. make it about twice the width or height of the display area, then move it across. loop this. because it's noise, nobody's going to notice a pattern. i don't know whether this is more or less efficient than using actual noise (as far as pd is concerned), but it's worked quite well for me.
the problem you might encounter is that it will look very precise, bitlike (in pd). any blurring method you can think of - like scaling it suboptimally - will probably work.

First of all I'm not sure if noise is the right word, but what I want to do is create that untuned TV station look in my gem window? Can anyone suggest a handy way of doing this which does not involve me taping 'snow' on my VCR and capturing it with a video card? Thanks in advance for the help!
