This is crazy cool. LED tattoos are the future of tattooing around the world. Yes I said LED.
LED Tattoos or a light-emitting diode tattoo is a type of body modification similar to a tattoo, but specifically involves implantation of technologically based materials versus traditional ink injection into the layers of the skin. LED tattoos are accomplished by a combination of silicon-silk technology and a miniature lighting device known as a light-emitting diode. While there is potential for many applications in the medical, commercial and personal domains, the technology is still in the development stage. But the lighting effects on your design is incredible. The tattooist that is leading the way is a guy named Keegan Sweeney. Here are a couple of examples of this incredible and new technology that is the future of tattoos. (warning: video contains mild nudity)
