World's first tattooing robot

An Austrian electrician has created a robot that tattoos humans. But would you trust your butt to a tattooing 'bot? The inventor says:

"It was a hard job because the only person I could test it on was myself which was painful but a good incentive to get it right as soon as possible…. He's an artist of course so he always decides what design the person is going to get, they can't choose. But I haven't had any complaints yet."
