[Air-L] Privacy enhancing technologies - user friendly design?

Hi all. Does any of you know some interesting models that accentuate/visualize privacy enhancing technologies? What I´m looking for are ideas that visualize PETs e.g. in the form of a traffic light (Red = not a privacy enhancing technology, yellow = mediocre, green = privacy enhancing) or something like that. The modular principle of Creative Commons and their icons is what I have in mind when it comes to PET visualization. Are there some more ideas, strategies, thoughts? Thanks!
