National Children's Museum

This guide to the National Children's Museum in Washington, D.C. asks who really painted the glowing maze called Light House, and traces it back to Washington artist Katherine Tzu-Lan Mann, who ran twelve workshops across the city and handed children the brushes instead of painting it herself. It follows what those kids pressed into the acrylic and glass panels, from a dinosaur with googly eyes to a Girl Scout troop number. Look for the spinning circles built into the maze before you move on.
