Audio descriptions are the only way that blind people can experience the works of art in a museum. Unfortunately, not many museums provide that feature and the general public is at large unaware of the issue.
To generate awareness and raise funds, Poland NGO Audiodescription Foundation invited renown Polish artists to donate some of their artworks and organised an auction. Only that on the auction day, the walls of the gallery were empty. Only audio descriptions of the auctioned work was available and the buyers could only see the piece after purchase.
These are the kind of ideas hidden in the brief itself.
