JC Sheitan Tenet lost his arm 22 years ago, which f**ken sucks no matter what, but is especially rough if you’re a tattoo artist like him. But fellow French artist and engineer Gonzal partnered with Tenet to create not just a prosthetic replacement, but an arm that could tattoo. They recently gave a demonstration at Tattoo Motor Show 8, a convention in Devézieux, France. Epic stuff.
