11 was shown for the first time in the exhibition "Finte nature" at Mac,n (Museo di Arte Contemporanea e del Novecento), Monsummano Terme, Italy. It is composed of eleven bundles of brambles falling from the ceiling. The work took up almost entirely the little room in which it was displayed, leaving just a little space for the visitors to enter. In order to dodge the brambles, the people had to assume a series of uncomfortable positions experiencing a variety of feelings: from fear to pleasure, up to the sensation of being in danger.
