This handy futuristic-looking device functions as both a tattoo gun and prosthetic arm. Designed by French artist JL Gonzal for tattoo artist JC Sheitan Tenet, the amazing, dual-purpose invention is the word’s first tattooing prosthesis. Fit with “pieces of a typewriter, monometer and pipes,” the epic machine was designed in such a way that Tenet can adjust it and alter the settings depending on his needs.
