A participatory audio-tour experiment

I was just directed to an interesting article on NYTimes.com: A Museum That Lets Its Visitors Become Part of the Art.

Halsey Burgund's exhibition "Round", at the Aldrich Contemporary Art Museum, offers up a museum audio tour that solicits contributions from viewers and gives them equal voice in the discussion of art.
... For [Burgund], the main point here is not so much to provide information about the artworks, but to create an experience that can enhance somebody's time in the museum. To take pleasure in this oddball installation, you have to countenance such a motivation and get past all expectation that you will learn something from the audio guide.
