Last Call is precarious: A stool, frozen mid-topple, with a pack of cigarettes attached to its side and a perfectly level bottle of beer balancing on top. Bloom 2 is a kinetic pun: A blossom of unwinding metal ribbon, powered by an antiquey motor—a spring flower. They are by sculptors Sean M. Johnson and Kirk Lang, both UW MFA grads.
