You have to see (and HEAR) this new trend in tattoos!
L.A.-based company Skin Motion is working on an app that allows you to record or upload an audio clip that will then make an audio file design. After the sound wave design is made, users can get it tattooed on their bodies by a tattoo artist; once healed, it can be scanned and played back on the app.
See the sound wave tattoo one woman got of her dog howling!
