"The Ole Barn Dance ... Music by the 'Mountin' Boys" – Musée Méchanique, Pier 45, Fisherman’s Warf, San Francisco, California

The Musée Méchanique is one of the world’s largest privately owned collections of mechanically operated musical instruments and antique arcade machines. Located at Fisherman’s Wharf in San Francisco, California, it consists of some 300 early 20th-century penny arcade games and artifacts including: music boxes, coin-operated fortune tellers, Mutoscopes, video games, love testers, player pianos, peep shows, photo booths, dioramas and animatronic machines. The machines require constant maintenance, with some having undergone major restorations. The collection is a for-profit interactive museum: While admission is free, visitors must pay for the use of each game. More than 100,000 visitors a year do just that.
