There have been a ton of what I would guess are intentional usages of Ron Paul Revolution branding. I saw something similar on an IHOP menu for one, the most memorable one for me though was when Newsweek ran a cover of Obama made up of tiny pictures in a mosaic fashion - which of course came but a few days after the full-page newspaper ad idea by a Ron Paul supporter for the Ames paper the day of the Iowa Straw Poll.
I imagine that the RP 2012 revolution, grassroots campaign, and ideas from volunteers reached alot of marketing 'top ten hot topics' publications and memos and such (I doubt they get it though

). It probably was, is, and should be used as an example of non-traditional / bottom-up viral marketing in all phases.
