Out of Frame · a night at the museum

Two bored cherubs leaned on their rail and jolted the whole gallery: the stars fell out of The Starry Night, the dots of La Grande Jatte came unstuck, and Venus drifted back out to sea. Step inside the masterpieces and restore them the painter's way — ride Van Gogh's swirling wind to carry the stars home, swap Seurat's dot-tiles until the colours mix in your eye, and be Zephyr, puffing Botticelli's shell ashore. Three paintings, twelve stages, all drawn in code.
