For seven years, a kinetic sculpture called "Blue" moved in quiet, continuous motion on the grounds of the Kennedy Center in Washington, D.C. — and last week, that motion stopped. Its removal, unannounced in its reasoning, invites reflection on the quiet negotiations between art and institution, between permanence and passage. Public art is never truly permanent; it exists on borrowed time, shaped by budgets, priorities, and the evolving vision of those who tend the spaces we share.
