Industrial designer Chen Chen collaborated on this deadly pop art creation with Kai Tsien Williams. Two cement-filled Budweiser beer cans join to create an unusual weapon. This piece is called American Ninja. Chen Chen has made a number of other strange and interesting creative designs including a vase made from foam, glass and rope, and a set of coasters that show cross sections of various materials.
