16. Worth ( - Statement of Defence) by Rebecca Bellmore, 2010
Nothing screams "political" quite like absolution. After a long legal battle with her former gallerist, Bellmore, one of Canada's more active and prominent artists, staged her exit from the art world in a gloriously commentative way. She showed up outside the Vancouver Art Gallery, scrubbed the sidewalk there, unfurled a bedspread of human hair, laid on it under a sign that read "I am worth more than $1 million to my people," then stood up and shouted, "I quit." The gallery had been trying to sue her for $1 million for four years.
