It may be that to have this space of transformation is only ever a concession to the uncompromising vision of the world sought by the likes of Dada and the Situationist International; in which the gallery system would be exploded, allowing the transformative effects of the gallery to flow out into their natural place: our everyday lives in the world at large.
In this vision, all spaces would be potential spaces of transformation, within a societal system that encourages mindfulness.
