The Saatchi Gallery's Iconoclasts: Art out of the Mainstream brings together the work of 13 distinct contemporary figures who examine what it means to be a contemporary iconoclast. As an act, iconoclasm historically holds both religious and progressive connotations. However, 21st-century culture has eroded the radicalism of this concept as artists are now questioning the intrinsic nature of iconoclasm itself by scrutinising what defines a work of art. A startling number of materials and techniques are on show, in which abstraction, figuration, creation and destruction combine. The exhibition runs in London until January 7.
