Built in Waldkirch Baden, Germany by A. Ruth & Sohn, the two-ton pipe organ was first exhibited at the 1900 World Exposition in Paris. Featuring 98 keys and 400 pipes, the organ has 18 lifelike figures that adorn the elaborately carved machine, with 12 of them spinning and dancing to each tune. It still runs on what it did more than 100 years ago... hand-fed cardboard sheet music.
