The Digital Tattoo Interface was another entry in the Greener Design Competition that the gravity lamp won second place in. It's an electronic interface embedded under the skin that looks like a tattoo. It's nuts. You could use it as a phone, computer, or traditional tattoo by downloading a picture of a unicorn from the internet. It runs on blood by turning glucose and oxygen into electricity. I don't trust it. Mostly because Jim Mielke, the man responsible for the concept, ends his spiel with "This product is waterproof and powered by pizza." Now get real Jim, who's going to believe that? Everybody who isn't a raving lunatic knows a digital tattoo interface can't run on pizza. Spaghetti-O's maybe, but pizza? You so crazy.
Two more pictures with words after the hop.
