Are museums finally truly opening up to public participation ? At New York’s Met museum, 450 employees are currently exhibiting their works in a large event that anyone can come and see. Meanwhile this summer at the Tate Modern in London, the public is invited to contribute to a large collective installation by Yayoi Kusama. Over in Austin, Texas, a museum curator encourages amateur bakers to create cakes inspired by the collections. Is it the start of a new era where the line between creator and visitor is blurred?
