Appropriate Audiences, a Paris-based design studio, has taken a 3D printer and combined it with a tattooist's needle to make an automated Tattoo "Printer." The studio took Autodesk software and turned tattoo designs into digital files that are downloaded into the machine. Then, a brave soul inserts the part of their body they wish to get tattooed and the needle starts working away at their skin. The needle is able to read and respond to changes in skin texture and the dimensions of the limb.
