I sometimes imagine doing an exercise where students would write down in a journal all the advertisements they see in a 24hr time-span. Every single one, including logos, brands, commercials, street signs. Anything bigger than an identifying mark for a store or object, anything that aims towards informing you about the company behind the object rather than the object itself. Of course fuzziness would have to be worked out (which itself would be part of the exercise).
In my mind, it is not as cool or clever as this. But more complete.
