An art critic accidentally destroyed a $20,000 sculpture at an art show in Mexico City. The sculpture consisted of a large pane of glass with objects like a soccer ball, a knife, and a feather suspended inside. Critic Avelina Lesper, who was unimpressed by the piece, allegedly placed her soda can on top of it, causing the glass to shatter. Lesper has apologized for breaking the sculpture, but told the gallery it should leave the shattered remains to show how the piece "evolved". The art gallery called the incident a "tragedy" and Lesper's behavior 'unprofessional'. Which is a more impressive piece of art - this sculpture or a banana duct-taped to a wall?
