Phonautograph recording of the oldest sound

Most gadgets that I write about are at the fore-front of technology. This Phonautograph, arguably, doesn't look like such a device at first glance:

But in 1860, when Parisian inventor Édouard-Léon Scott de Martinville used his device to record Au Claire de la Lune, it was definitely cutting-edge technology, as his device predates Thomas Edison's work by 17 years. One recording from the above device has now been recovered and can be downloaded as an MP3 file almost 150 years later, and subsequently be played on your computer, or even your iPod or iPhone.
