The basic concept is very simple: take existing advertising slogans, parse them out and mash them together - with the appropriate syntax and semantics - to create another slogan, then link to an appropriate picture on flickr.
The result? - A completely new advert.
As the creator says
By remixing corporate slogans, I intend to show how the language of advertising is both deeply meaningful, in that it represents real cultural values and desires, and yet utterly meaningless in that these ideas have no relationship to the products being sold
Very clever idea, and one which works well!
