The Museum of Marvels (Free)
Free forever. Walk eleven rooms from the magic lantern to the machine in your pocket: the ghosts of 1790s Paris, the toys that taught pictures to move, the night of December 28, 1895, the magician who stayed in his seat, the first glass studio, the tricks, the fall, the rescue, and the heirs. Every generation gets a new apparatus. This museum exists so you recognize yours.
