13. The Propeller Group, ’AK-47 vs. M16’, 2015

Vietnamese-American artist collective The Propeller Group’s ’AK-47 vs. M16’ (2015) is a re-creation of the one in a billion chance of two bullets, shot from opposing sides of a battle, colliding into each other. The colliding bullets from an AK47, invented by the Soviets, and an M16, the brainchild of the U.S. army, highlights the horrifying scale of wartime and political violence throughout 20th century history.
