Light Filters?

I believe that the effect of the static, as well as the piece, is

 greatly enhanced by darkness and also through filtering, giving the static a much more interesting and blurred form. So to enhance the effect of the static there are two different paths that I could go down. I could either create a frame covered with white cloth or perspex (similar to some of Brian Eno’s installation work) that goes all the way around the television, creating a very ambiguous feel, or I could, perhaps using white paper, simply attach a square filter that would be placed only on the glass of the television screen. Which paths I go down depends on the final aesthetic affect that I wish to go for. Do I want the Television to become an ambiguous and mysterious source of light? Or to I want the television to be instantly recognizable to the viewer? I will probably test both methods and see which one is most effective in conjunction with the piece I will have created.
