Tattoos are works of visual style. But what if they had other functions that can't be detected by the eye? Such is the inkwork on Dmitry Morozov, a visual artist. He has a tattoo on his arm that serves as a barcode that can be scanned by a homemade sensor. The sensor, while reading the code, plays music at different tonalities, from a "theremin squeal to the low moan of guitar feedback.” And as reported by consequenceofsound.net, the build of the sensor is relatively simple: "the device uses two black line sensors available at most hardware stores, a basic stepper motor, and parts of a Wii remote." Could this be referred to as a multi-media tattoo? And is it the world's first? Check out the video to hear the amazing sounds that are coming off of Morozov's tattoo.
