Among the conceptual works that base their appeal on the paradox, NaDa well represents the world's commercial software industry and its representation in a browser window. NaDa, in fact, is presented as a product 'that does absolutely nothing', which cne brings forth a reassuring presence, as opposed to the dark tasks of the software. Immateriality of the product is the packaging, given by the graphics and the interface in general is that the credibility of what you offer, long before the actual verification of its consistency.
