A guerrilla performance
Venice, Moscow, London, São Paulo, New York
Museums and exhibitions are always lead by directors and curators but there are no limits for the artists bodily making themselves a part of this or another exhibition or institution in general - it only takes their physical presence, the magic of appearance.
Repeating the scheme of a foundling - an envelope with a baby left at the door of an orphanage - I lock my body in a small and claustrophobic glassbox. It's safely sealed and screwed so the only way to open it would be either to break it or to open it using some specific instruments.
I ask my good friends to bring this glass box with my naked body inside of it to the door of a museum. They should then leave the delivery and run away before anyone could stop them.
The further scenario entirely depends on how well organised is an institution.
