Artist Bartholomäus Traubeck has custom-built a record player that is able to "play" cross-sectional slices of tree trunks. The result is his artpiece "Years," an audio recording of tree rings being read by a computer and turned into music, much like a record player's needle reads the grooves on an LP.

The tree rings are actually being translated into the language of music, rather than sounding musical in and of themselves. According to Makezine, the custom record player takes in data using a PlayStation Eye Camera and a stepper motor attached to its control arm, and relays the data to a computer. A program called Ableton Live then uses it to generate an eerie piano track. [Listen to the Six Spooky Sounds from the Deep]
Though the record player "interprets" rather than actually "playing" the tree trunk, as Gizmodo notes, the song still varies with each new piece of wood placed on the turntable.
