This wooden Leica is a covert music box with rotating 'lens'

Unlike some of the camera replica projects that have surfaced over the years, this wooden Leica music box is available to purchase now. The music box, which is available from multiple sellers through online retailers Amazon and eBay, features a combination of wood components and wood burning to imitate the Leica M camera system.

Different versions of the music box are available, including options that play Für Elise, The Blue Danube, and more modern tunes like the Harry Potter theme song. Users wind the music box by rotating the front lens, which then slowly unwinds as the music plays. Prices vary based on seller, but generally sit around $12.
